Act like you are shipping them - put them in a pillowcase (so some other cloth bag with some crumpled newspaper) then put the bags in a styrofoam lined box. This will keep any direct air from getting on them, keep them feeling secure and keep them warm.


You should set this up ahead of time and put a thermometer probe in the box (without the snakes) and go for a drive. This will allow you to monitor the temps for a couple of hours to see how hot/cold it gets in the box then you can correct any issues (add heat or cool packs to the boxes as needed to maintain a good temp).
