Wow, I received a few more replies then I thought I would.
There is a brand new hall near me that has a large parking lot so it's not like you'll have to park a block away. It has tables, chairs, a kitchen and bathrooms (male and female). The hall is located just north of Grand Rapids. The only thing I need is $1.00 per person for rent. Anything over will be donated to this site.
I'm thinking about June 12th which is a Saturday. This is the weekend after the IMAC in Chicago.
I figure that some people that went might came back with some big pieces they could frag off to trade for more stuff.
Let me know soon so I can place a reserve on the hall.
