Sculpture out in the High Desert, off the beaten track, down a dirt road. Some whimsical, some funny, some serious, some goofy. An amazing site, actually, with an interesting history behind it. Off the wall. Bring a camera.
Free and you can just park across the street and walk in. Wear comfortable shoes for the desert sand, and be cautious of the abundant pokey cacti.
Suggest early AM, as it can get pretty hot up there.
Bring water. Also, saw no bathroom facilities. The site had no supervision at the time we were there, so couldn't ask.
