I don't know the attendance rates of other fairs, but I've seen ours estimated at 30,000+ attendees and 400 exhibitors. County Fair is at same fairgrounds and has a little more attendance, but with the livestock exhibitions there may be more "chicken people" at that one than the Home/Garden Show
County Fair "Home Shows", there are lots of them around the country throughout the year. My county has at least two per year at the fairgrounds and there are lots of different vendors
