We show there all the time, very nice, parking ok(can run short of parking and have to park in lower lot but they do have shuttles from lower parking lots), it is handicap assessible, Grooming and show area very good, drop off/pick up very good, walking would not be a problem
Questioning, you said you were thinking of showing there late this year, as far as I know after September there won't be any all breed shows there until after the first of the year, the Edwardsville Kennel Club show in December is at the fairgrounds in Belleville. Belleville is not as nice as Purina, but having to walk a great distance is not a problem
