In all seriousness, you should have great weather and the mammals are not what I would warn you about if you venture into the desert this time of year even for a picnic. This is the time of year when you encounter rattlesnakes sunning themselves during the day. In the summer when it is hot they are more likely to be active at night. Same advice as javelina - you are too big to eat. They just want to get away from you. If you hear a rattle, freeze, figure out where it is if you can, and back away! If you don't know what a rattle sounds like I bet youtube would be helpful.
Again, it is something to educate yourself about and be prepared for, not something to worry over.
As they say, the most common words spoken before a rattlesnake bite are "Hold my beer and watch this."
