I'm pretty excited to see so many in Grand Rapids, too. I love the idea of a trading thread, but unfortunately I don't think I'd be able to contribute anything worthwhile for awhile (unless people like/want art, ha).
But I enjoy supporting local, so if I can't trade yet maybe then I can buy trimmings! Or shrimpies. I really want to have some shrimpies in the tank, but I still need to research if any of my target fauna will pose a major threat to them.
ETA: I'd never heard of Pruess, but I'm going to be driving across the state tomorrow. I'll see if I can convince the hubby to make a detour stop to check it out if you guys think it's worthwhile to see (even if I can't buy livestock/plants yet).
