best place to identify local sportcard shows?

I was at a show in Minneapolis, and a dealer was talking about some big show coming here? What sites do y'all use to find shows coming up in your area? Anyone hear about a big one coming to Minneapolis or St. Paul? Thanks.

Gracias - that's gotta be it. I got married where they are having it, so at least I should be able to find it. Pricey auto's though - or maybe I'm cheap.
