I would dare say that trying to board a plane with a pile of snakes wouldn't be an easy thing to do for awhile, not with everyone screaming "Snakes on a Plane!"
You could probably get a snake with exactly the right hets you want at a show like Daytona, but it may depend upon what hets you're looking for. Some of the big breeders, like Rich, don't label all the hets of each hatchling. The higher end morphs have hets labeled, but not the lower end stuff. You can find breeders that know all the hets for every hatchling, but whether they have them labeled at a big show or not could vary as well. Then there is the time needed to hunt down that particular snake. The number of vendors, snakes for sale and people attending the show may not be overly condusive for such a search. You could get lucky or go home empty handed. So what I'm trying to say is that shows like Daytona are terrific and you can almost always find something, or lots of somethings, that you want, but don't rely solely on it. Use the web as well for that one particular, extra-special snake.
And congrats Craig! August is the perfect month to be born in. But you're going to have your hands full with a Leo boy!
