Ok, who switched my horse??

Well, I took him for a ride through my backyard and fields and he was a "good ol'Cowboy". No shenanigans like last Sunday. I wonder if he was like that because there were 5 other horses? Well, he's gonna have to learn to deal with it, cuz its way better to ride with a group in these great places than just in my postage-stamp yard. I'm graduating to working on loping on the longe line, but need some pointers of how to make corrections. Funny thing is he is very tempermental about going to the right at lope. He started in with the old stop and back up routine. He lopes to the left much more willingly. (Opposite of his trot history...??) My bow practice has fallen flat because I can't get the rope to stay on his foot long enough...it keeps slipping up his leg. He does try, so it's still there...but very uncoordinated. (me, that is...)
