There is a very small patch of woods behind the farm my horse is at. I try to do the exercises I do in the arena out in the woods to give him a change of scenery. Seems to give him more to think about (stepping over branches, working around trees, stealing a mouthful of the nearest green thing) He used to be spooky of back there but relaxes wonderfully now and seems to enjoy working in there, I like it to. Maybe if you have an area like this, he would like that. I'm also interested in the responses you get!
