check out their site for the show, gives you a good idea of what to expect as far as vendors, demonstrations and so on...
at the ones i have been to up here i have seen people that have brought in their own pets to show off or to trade/sale (w/e other reasons) but personaly i would not just for the QT reasons alone.
like it or not there are some of the good guys and the not so good ones at those shows so it is always best to air on the side of caution when it comes to your animals.
you have already stated you wont have money to get anything (LOL and that can be a plus for your first show) but by all means go have a good time looking at all they have to offer, talk to some of the vendors get some first hand info... use it as another way to learn first hand some of the things you have possibly been wanting to know.
