Since snakes are cold blooded this makes them the ideal hibernator. Being from the northeast (upstate NY- WHOLE LOTS OF SNOW) it's pretty cool to watch nature at it's best when spring comes around.
If animals like snakes, lizards, frogs, fish, all cold blooded could not hibernate (actually most burry themselves in the mud) then we would have run out of fish, frogs, toads, snakes a long time ago, yet froggies get it on in the spring, fish fill the ponds, etc.
When winter comes, these animals don't need massive food stores because the are capable of slowing their metabolic processes. This means the need for energy from food and fat stores reduces dramatically. They just let their temps lower, slow things down until the warmth comes back.
NOW, you want to talk about cool hibernation (because cold blooded animals are suppose to be able to deal with low temps), do some research on bear's. They are warm blooded and hibernate too for months and months. From what I understand they lower their metabolism quite a bit for the winter but unlike reptiles require massive fat storage to survive the winter of "sleep" because their min. temps can't decrease safely as excessively as reptiles.

BOTTOM LINE: If you don't have access to local breeders and can't afford an online breeder and really want a snake keep it. The east coast has been receiving a "hurricane season" for millions of years before we got here and the snakes have survived just fine. In fact snakes out-survived the dinosaurs. They can definitely handle a little water.
