Well, if you take your snake, you will have to take all his stuff- his viv, UTH, thermostat, food, etc. How long do you plan to be gone for? You would have to protect the snake from heat and cold- which would mean not leaving him in the car if you are up north. Is he a baby, or an adult? An adult could travel comfortably in a pillowcase, tied shut, (check the corners to make sure there isn't the tiniest hole) and then you would put the pillowcase in either a cooler or his feeding bin if it is large enough, to protect him from accidental crushing. A baby I would put in a deli cup or his feeding container, with crushed paper towels, with the deli cup taped shut, and then put that in a box of crumpled newspaper to prevent jostling. Then put the snake in a cool place in the car, not on the floor, not where sun will shine on him, not where heat will blow on him. Obviously not in the trunk or anywhere that isn't heated.
