Lucky! Here in Alberta we have like no expos... anyways, some things you may want to ask is hatch date, eating live/ft (if that concerns you) some things you want to look for on the snake is no stuck shed, you can also grab a damp paper tower or something and rub it down the snake to check for mites... Make sure the snake is active and tongue is flickering etc... If you have any other questions let me know and ill do the best to my knowledge.
