A friend of mine made some pretty kickass looking Illinois ID cards last year. He couldn't take a little time out to make ME one, of course. He used the state logos and the black light ink and everything. They were beautiful.
A few times, back in the 90's when I worked at various convenience stores, they would give us training on how to spot fake IDs. In one class, the lady said that a good place to get the IDs was at a flea market. She also said that the law stated that those places could sell fake IDs, as long as they were for a state other than Texas. (We were in Texas at the time.) So I guess you're not supposed to sell fake IDs representing the state that you live in. This was back in '95, though, so laws could be different now.
