Here's a vendor list for that show to help you or if any members here have experience with any vendor listed and wish to offer advice/experience with that vendor.

It's great you are taking your time and doing the research/set up of the enclosure first!

A normal male BP (non-morph) is an excellent pet snake. If you are intending to breed at some later point you may want to think about a female normal 06 hatchling and raise her for 3 years or so to breeding weight. There is no real temperment difference I've ever heard of between males and females. Females tend to get a bit larger but some males can be quite hefty too...genetics plays a big role in that.

Basically, whatever you decide you want a healthy captive born snake. A good breeder will take the time to tell you about the snake, not just toss it in a bag and grab your cash. You should be given it's hatchdate, feeding preference (mice or rats, frozen/thawed, pre-killed or live) and an assurance it's been properly sexed. The snake should look healthy with clear eyes, no retained shed, a clean belly and vent area, girthy with no pronounced spine or triangular look to it. For me even baby BP's feel surpringly heavy for length (different say to a baby colubrid). No indications of mite or ticks on it or any of snakes that vendor has brought. No raised scales/scale damage, the snake should feel soft to touch but very muscular even if it's a baby. Check the vendor's display. Does it look clean, well setup and professional. Does the vendor seem knowledgeable about the snakes he/she is offering for sale. Did the vendor actually breed this snake. Ask lots of questions and if you get any niggly feeling, move along to another breeder. Check out a few vendors before making your final buy. If you are handling a number of snakes, ask for hand sanitizer between each vendor's snakes (most will have it right on their table) or bring some yourself.

It's better to come home from a show with nothing than bring home a sick baby. We did that once only...fell in love with a hatchling....got a bit of show fever and brought home a snake without being this careful. Shortly thereafter she died in our hands and you certainly do not need that experience. Always quarantine any new arrivals from any other herps you own.

You may want to pick up a travel container, put in a small old towel and inside the towel where the snake cannot get into direct contact with it, put one of those instant shake and heat heat packs you can get from WalMart or any sporting goods store. Here's what we use for transporting snakes and even to pop them into while cleaning their homes. You can find these in any size from dollar stores, WalMart, Meijers, etc. for $2 - $10 depending on size. Just make sure to add in vent holes for air movement.
