Around sunset during the warmer parts of the year I've come across up to 5 rattlers in one ride on the desert classic trail. I've seen them up telegraph as well by the stone house. definitely see a lot of them out there.

Got buzzed by a black western rattlesnake by the creek going into Haunted Canyon yesterday. he gave me plenty of warning. Same here, only about a half mile passed the trough when you first get on the trail. Didn't see him at first but he definately let me know he was there with about 4 feet to spare.
