Please please PLEASE be careful!!!! I was traveling three hours with my first snake in a car, and it turned out it was too hot and he died. DO NOT keep your snake in 95+ degree weather FOR MORE THAN A FEW MINUTES. It's pretty warm in Texas this time of year, so you'll want to use your air conditioning. Just keep the snake in a small container, and put that inside a styrofoam cooler. If you are using no air conditioning, put a small ice pack on one side. If you are going to be leaving the car with no air on for any length of time, TAKE THE SNAKE WITH YOU. Like, if you stop to gas up your car, make sure the snake's container isn't in direct sunlight and you don't go inside the gas station to eat or whatever without taking the animal with you. The snake will be fine with no other heat source for the length of the trip. It is better for him to be a bit too cold for a while than it is for him to be too hot and...well, dead. PLEASE don't make the same mistake I did!
