FYI,
there is a den of copperheads at the base of Electric Cowboy/Burden of Dreams. After the trail leads up to the ledge and you turn right to walk around the corner to the climbs, there is a large dead tree that you have to walk over to climb onto the boulders benieth the routes. The snakes are around, on and under the tree. They were pretty agitated yesterday(jumping and snapping, etc.). Coincidentally, this is right where you lower off for electric cowboy.
