Wyoming is correct. This arch is at a motel just across the street from the Jackson Hole Greater Yellowstone Visitor Center in Jackson Hole Wyoming. There are four more antler arches on the square in downtown Jackson Hole. Norma snapped a couple on the square as we drove by.
Wow! It's hard to believe all of those are real! What, does everyone in the town just donate their findings to the city to build those or something!? Huge elk farms? I can't wrap my mind around it! Lol
