I've been mulling over the idea of having a riding arena... but cost is going to be a huge concern. I really don't need anything big, I just need something I can use in the lovely wisconsin winter, mostly wt, maybe an occasional canter. What's the smallest size you'd recommend? I have lots of family with large macheniery, so I think the leveling/preparation cost would be very little, so that's great! Also, we have alot of amish that build barns and homes in the area, has anyone ever had them build anythhing like an arena? Has anyone built their own arena to save $$$$?
