Lafayette Township, NJ
A life-size bronze replica shows the famously loyal Japanese Akita Hachiko joyfully reunited with Professor Hidesaburo Ueno. Installed at Abbey Glen Pet Memorial Park in 2016, it reproduces the paired statue created for the University of Tokyo.
Hackberry, AZ
Vintage gas pumps, signs, cars and roadside debris crowd this former Route 66 service stop. The store and its yard preserve the dense visual language of the highway better than a polished recreation would.
Haddonfield, NJ
A life-size bronze Hadrosaurus foulkii stands downtown in honor of the dinosaur discovered nearby in 1858. Nicknamed Haddy, the sculpture gives Haddonfield a visible prehistoric mascot linked to one of the most important early dinosaur discoveries in North America.
Hagerman, ID
Designated public overlook across the Hagerman fossil landscape and Oregon Trail corridor. Fossil collecting and off-route access are prohibited; OddWay should keep users at signed public viewpoints.
Volcano, HI
A boardwalk crosses a hydrothermal area stained yellow and white by sulfur minerals while steam and volcanic gases rise from fractures. The landscape can smell strongly of sulfur dioxide and hydrogen sulfide; people with respiratory or heart conditions should follow park health guidance.
Hellam Township, PA
Shoe magnate Mahlon Haines built this five-level work-boot-shaped house in 1948–49 as an enormous advertisement and promotional guesthouse for his shoe business. It is now a short-term rental rather than a public museum: **only registered guests may enter**, although the owners explicitly welcome photographs from the public roadside.
Kula, HI
The summit area of Haleakalā rises above 10,000 feet over an enormous erosional crater filled with cinder cones and lava landscapes. Weather, altitude, park rules, and sunrise reservation requirements can all affect access, so conditions should be checked before routing.
Port Lavaca, TX
A compact 1850s screw-pile lighthouse that once stood in Matagorda Bay is now preserved on land near the Port Lavaca causeway.
Anderson, IN
Outside an Anderson collision shop, automobiles appear to dive nose-first into the ground alongside large dinosaur figures and other automotive art. The display sits at an active business at 1400 W. 29th Street, so it is best visited during normal business access rather than after the gates are closed.
Honolulu, HI
Ocean swells force water through a lava tube and blast spray from a hole in the coastal rock beside Kalanianaʻole Highway. Conditions can turn dangerous quickly; use the established overlook and never stand directly over the blowhole or enter rough surf below.
Gloucester, MA
Inventor John Hays Hammond Jr. built a medieval-style seaside castle as his home, laboratory and showcase for antiquities. The eccentric structure mixes genuine old architectural fragments with twentieth-century technology, and current programming even explores Hammond's experiments involving parapsychology and Spiritualism.
Hamtramck, MI
Ukrainian immigrant Dmytro Szylak spent decades filling the space above and behind his garages with whirligigs, wooden figures, airplanes, lights and handmade moving sculptures. Hatch Art now preserves the folk-art environment, which can be viewed from the alley and has scheduled volunteer restoration days. Address: 12087 Klinger St., Hamtramck, MI
Hāna, HI
Visitors descend into a privately operated lava tube formed by flowing basalt, where frozen lava textures, chambers, and ceilings preserve the mechanics of an ancient eruption underground. Entry is ticketed and should follow the operator's lighting and footwear guidance.
Hanapēpē, HI
A narrow pedestrian suspension bridge sways above the Hanapēpē River behind the historic town center. It is a compact piece of plantation-era infrastructure turned local landmark; because Kauaʻi is recovering from Hurricane Lowell, verify the bridge and surrounding access before routing.
Grand Rapids, MI
A small plaque beside the Grand River commemorates an event that never happened in this universe. It belongs to Eames Demetrios's worldwide Kcymaerxthaere project, which installs physical markers describing people, places and events from an elaborate fictional parallel world.
Lagro, IN
Hanging Rock is the exposed remnant of an ancient coral reef formed hundreds of millions of years before Indiana existed as dry land. The limestone bluff rises abruptly over the Wabash River and is protected as a National Natural Landmark.
Waiteville, WV
This former fire lookout sits on a narrow ridge reached by roughly a 1.2-mile hike and became a famous place for watching migrating hawks and other raptors. The trail remains open, but the tourism authority currently reports the observation structure itself as temporarily closed, so check status before building a route around it.
Harborcreek, PA
A field of large metal sculptures on Bartlett Road east of Erie: a tyrannosaurus and its young, a triceratops, a woolly mammoth, and a welder among them. They stand on private land beside the road, so look from public ground rather than crossing the grass. Catalogues of the work list it under North East, which is the wrong township and about ten miles off — this entry is placed from the sculptures themselves.
Bloomington, IN
Indiana University's Psychological and Brain Sciences building has a seven-foot-tall, roughly 10,000-pound human brain carved from Indiana limestone outside its entrance. Artist Amy Brier and carver Mike Donham created the anatomically detailed sculpture, nicknamed Harlan, for the department's 125th anniversary.
North Adams, MA
Resonating tubes mounted beneath a highway overpass transform traffic vibration into a low, continuous musical drone. Instead of hiding road noise, artists Bruce Odland and Sam Auinger turned the bridge itself into a massive instrument.
San Diego, CA
A private front-yard hedge has been clipped into dozens of animals and geometric figures. View from the public sidewalk and respect the residence.
Dinosaur, CO
At the end of Dinosaur National Monument's Colorado-side scenic road, a trail reaches a high peninsula above deeply cut canyons and dramatic folded rock. The overlook exposes the strange geology of the monument far beyond its dinosaur fossils.
Havelock, NC
Havelock’s close relationship with Marine Corps aviation is represented by a static AV-8 Harrier display in town. In 2026 Fleet Readiness Center East also restored and moved a two-seat TAV-8B Harrier to the Havelock Tourist and Event Center, adding another retired jump jet to a public collection of Marine aircraft. 2026 update: https://www.linkedin.com/posts/fleet-readiness-center-east_frce-fleetreadinesscentereast-av8bharrier-activity-7496225697993175040-6J6o Coordinate reference: https://virtualglobetrotting.com/map/mcdonnell-douglas-av-8-harrier-ii/
