As a midwestern-er myself, I have been through many an a-rated show. Though most rated shows are located on the coastlines, the Midwest has Maffit Lake, Showplace, WEC, MN State Fair and a bunch more. Otter Creek has shows periodically that are rated hunter and jumper shows. My personal farm hosts a few but we have two (almost three) farm locations across the US and aren't consistent with our shows in the Midwest. If the rated circuit is hard to get to or too expensive, many local farms do the Marshall and Sterling League which is nationally recognized and offers some payout classes like a rated show! Hope that helps!
