The gaping of the mouth thing was actually her chewing on the bit. As you can see, I'm posting up, and I never have a hold of her face when I'm in the "up" position. My trainer forbids me :P. I agree with you about the tight hold though, I have a bad habit about that when she's hyper and we're working on it. The good news is she's only in a french link snaffle
I've been thinking about 3 day A LOT. She has shown so much athleticism and heart towards cross country. I really want to start her over hunters for the training for about a year. I want her to be able to do a course with a relaxed frame and a slow pace. That way, if I do have to sell her, anybody (well, almost ) would be able to ride her. Then, I want to move up to dressage, jumpers, xc.
This was an off day for us, I'll try to get better ones of us on a normal day. Because we really don't look like this all the time :P
