I'm new and just got one of those. >.>
But yeah, I know what you mean. Even in Florida here (where everything's on the humid side) the tanks are kept pretty bare. Then again, they're often shipped and are under a little bit of stress at the very least. Never mind that they don't seem to know how to feed them properly - I was told to give pinkies to my ball when she was actually underweight(another thing they didn't catch) and hoppers were more appropriate. Occasionally you'll get one guy or gal who knows their stuff, but you're better off buying from a specialty store. After all, PetSmart's a department store and therefore covers a lot, and herps are in the minority.
