Have not seen any snakes yet, but a head's up: You may want to avoid attracting scorpions to your rig. They enjoy dark places to hide (things to hide under) a lot of water on the ground, and a lot of bugs. So, if you keep around your rig clear of clutter/ground cover, dry, and clear of food debris you are going to be in a much better position.

I've stayed 2 seasons so far and saw a snake once. I never walk where I can't see the ground in front of me. I would say there is no huge issue with snakes.

There are snakes everywhere in the desert, but I did not encounter any during the three months I was there.
