Medina County, around 30 miles southwest of Cleveland. I go down to a very good toy show in Greenville every fall with a friend (he lives about an hour from me so I only have to drive 60 minutes instead of 4 hours) so I'm familiar with Celina. We usually stop there for dinner. Grand lake of St Marys out there is neat. Brother and I went to a farm toy sale out by Greenville last summer that had a lot of Oliver and White on it. Saw a MM Plainsman 4wd by Cottonwood Acres bring $2700! Nice tractor but that was over double of what I wanted to pay. if you are ever in Ohio third weekend of March you should check out the Fremont toy show. That is a big event.
Where are you at in Michigan? I went up there for my work over the winter for a week. To the U.P. (Copper Harbor) actually. 1600 miles round trip was interesting, especially hauling a trailer!
