6 or 8 years ago, I was a security supervisor at the Chrysler automotive test track here in Arizona. Part of our job was to relocate the rattlesnakes that got too close to the building (like under the shop foreman's desk). I still have some friends out there. One of them sent me some pics of a Tiger Rattlesnake (Crotalus tigris)they had to move. This was a big one, closing in on 3 feet long.

The pics were taken by Twodogs, who still pokes his head in here occasionally.
