Desperado, I did that once up in Walla Walla County. I was at a remote repeater site and in the process of opening an old GE cabinet. Since it was a half height cabinet, I was squatted down and as I turned the key and opened the front door, a bull snake struck at me from within.

After I got my heart started again, I turned him into a greasy spot on the concrete floor. Normally I like bull snakes and enjoy having them around, but I had to do something to drain the adrenalin outta my system, and besides he started it.
