I forgot to respond to the question about places to ride in Ohio. I lived in Columbus in my pre-horsie days, so I don't know specifics about trails that allow horses. However, there are a lot of rail-trails in Ohio, some of which allow horses. Do a search for Ohio "Rails-to-trails" online. There used to be a guide to them published every few years, you might see if there is a reasonably current one you can get. Even the ones that don't allow horses are worth looking into for running and bike rides. I miss that about Ohio so much! Thinking about it makes me homesick!
I was normal...then I got a horse.
