UFO Crashed Here Sign (Gone)
Northwest Chaves, New Mexico
The Roswell UFO crash actually happened here -- many miles north of town. You can't visit the site without a private tour, but you can take a picture of the relatively large "UFO Crash Site - No Trespassing" sign. The exact spot is about eight miles west, where dead alien bodies and a wrecked saucer were supposedly found in June-July 1947 (The exact day is still debated). Roswell has three other supposed saucer crash sites as well, but they're too far away and too visually unrewarding to bother with. Stick with the sign.
