You aren't crazy at all! I heard of one guy who rode and ponyied a second horse. I think he was doing it for a charity, he raised money to donate once his expenses were taken care of. I think he rode to the capital buildings of cities he went through to prove a point. I don't remember now. Anyway, maybe if you do it for a charity it would help with expenses. He had a website and someone would put up his whereabouts almost daily. Fairgrounds are a cheap place to spend the night and of course there are books on places to stay with your horse while going across country. I would wonder about how to plot out the trail so you don't have to cross highways, I would think that would be the tough part. No books on that.
