Same snake (Western Diamond-backed Rattlesnake) that we had in the area a couple of days earlier.
See http://www.pbase.com/pegsam/image/124985799 . This is a shot after it had just finished consuming
a young Round-Tailed Ground Squirrel. And, yes, this is a macro shot with me about 3 feet away.
Please do not try to get a close-up shot like this unless you know what you are doing and are
prepared to deal with a potentially deadly bite. There. You've been warned.
