1 No im in colorado But i will give my info based on what I have seen.
2 no clue
3 It depends on each vendor. Some will some wont. IF you have them hold it make sure you bought it. I have seen snakes put on hold then get sold to the next person with money. Personally I would carry it. If nothing else take a back pack to carry the snake in just make sure it doesnt get to hot and has enough air.
4 If you can deal with the teps try to keep your car about 87ish. They should give you a plastic cup or a bag to hold the snake in. It should be ok in there.
5 Personally I like to keep em in a seperate tub on the other end of the room or in a diff room. Just to make sure.
6 the biggest thing I can reccomend is HAVE FUN. Try to be there towards the end of the show as the sellers will alot of times drop the prices some. The show should have a website. Check out what breeders are going to be there, check out the vendors ect. WEAR SHOES YOU CAN WALK IN.
