Really cute. I'm nervous when I ride my mare outside the arena. It's an unfortunate reinforcing cycle- she's nervous, which makes me nervous, which makes her nervous. And on we go.
Last week, I hacked out with someone else, thinking being around another horse would help my mare. The other horse is a placid 25ish year old guy who is as easy going as they come. Wouldn't you know it, he acted like an unbroken greenie out riding around the pasture and the both of them were so hyped up it totally backfired.
The only (potential) excuse for them was about 15 minutes after we were done riding, we heard a huge pack of coyotes just a few feet into the woods near where we were riding pick off some kind of prey. Maybe the horses had a legit reason to be on their toes. Still though, I've got to get over this problem, because riding laps around the arena just isn't fun for anyone!
