Expo is the one that started it all. I try to go every year. Have to miss this years due to work requirements. The Midwest Gaming Classic has a lot of pins. Pinball at the Zoo in Kalamazoo is a nice smaller show. The best pinball player "show" is the VFW Showcase. Play an assortment of 225+ machines. Next one is scheduled for May 15-17, 2015. This show restricts ticket sales so there is no overcrowding like at most other shows. www.vfwpinball.com
