It's still hot but I managed a half day in Anza-Borrego searching for pictographs and climbing Grunt BM. The highlight was a pair of bighorn rams, one bashing his head against to cactus to break it open and eat the juicy insides. I didn't know they did that. Link to video at the end.

That's no flapjack rabbit, but still pretty cool.
