I was leading a climb today out east. I was almost to the anchors, and all of a sudden a rattlesnake dives by me to a small bush. It literally dove off a little ledge by the anchors and went past my head on the left. Then it sat there and stared me down. I threaded the anchors with shaking hands and then slowly lowered, there was a draw about 4 feet in front of it and i was determined not to loose the draw, so I stared back at the snake down and talked to it in a calming manner and got my draws back. The guy I was climbing with, Tim Wilson, he was determined to do the climb and got up under where the snake was and said "That is a really big snake, holy shit." he lowered from there, spooky. Be careful out there of flying snakes.
