If you're in northwest Ohio, head across the state line into Indiana and hit the auction at Shipshewana (Did I mangle the spelling? Probably) and find damn near any price from "bad song" to "king's ransom", on every flavor of equine you can dream up, from just-weaned minis, to burnt-out Amish belgians and standardbreds, and every possible variation in between.
You'll have to do your own legwork to find dates, times, etc, but I can guarantee that when the auctioneer starts singing, there's something for ANYBODY interested in buying a horse at Shipse.
Mackinac Island, MI gets a shitload of the horses they use from Shipse - Just beware... One of the several years I was there, Dale Gough picked up three teams of absolutely GORGEOUS Amish-broke Belgian 6, 7, and 8 year olds for less than 10K. One of them ended up being my team that summer, and a nicer pair to work with would be hard to find again. Practically "pushbutton" ponies that I could tie the lines to the brake and just talk to 'em to drive all day long. Of course, a couple years later, Nancy Byrd went down and thought she was gonna pick up some stock, and dragged home a couple of the butt-ugliest, ill-trained (probably closer to "barely trained") black percherons that I got roped into trying to teach how to handle life on the island. She never did say what she gave for 'em, but when she sold out to Ryba and vanished, Dick sent 'em to the packing plant ASAP. Couldn't trust that pair as far as you could spit, they NEVER lost their "spook", tended to decide "Eh, we're bored here, so we're just gonna start walking" while you were trying to load/unload the dray... A bigger pain-in-the-ass team I don't think I've ever had the misfortune to drive. I'm amazed that they never went full-blown runaway. (That was Jim Pettit's year for runaways - His team got hit by bicycles screaming down fort hill twice that summer - the first time, the damage was just under 30 grand worth of smashed bicycles and street-lamps, and a totally destroyed (but fortunately, empty) baby stroller, the second time cost him a broken arm and a massive case of road-rash as he managed to catch the lines, but then got bounced off the side of the dray and run over/dragged - That time, the team managed to stay more-or-less in the center of main street, and didn't do much property damage beyond the bike that some idiot literally picked up and threw in front of them in hopes it might stop them - it didn't... but had to be chased most of the way to the library before someone was able to get aboard and haul them down.)
