What kinds of ailments/ illnesses / injuries do you see most... where do you find out about animals in need?

I'm new to the BP thing, but I'm not new to rescue... the more I learn about BPs, the more I realize that many other people just listened to what the pet store employee told them and don't get out there and really try to understand their needs the way the people here do... and I wonder... what becomes of their snakes? I'm sure more snakes than we care to consider die in incapable hands (or just hands of the ignorant or whatever) but there have to be others out there that can still be helped... I don't want to start a snake rescue by any means, but I feel I'd be a good foster parent if there were needy snakes around me...

Anyone here do rescue and have any info for me? I'd sure appreciate any discussion on the subject... thanks in advance...
