For those of you within a couple of hours of Cincinnati -- they have a miniature show on April 11 & 12. I wasn't going to go as Chicago is the following weekend, but decided to get two tables and give it a shot. The link and flyer for the show are below. There should be around 25 dealers there (from what is listed on their website).
Forum members get a deal at my tables (All About Miniatures) be sure to come say hello!!
