Thanks guys. I feel better, now. I had very few problems with Dancer on the trail - she was one of the better behaved ones, in fact. Not to mention it was her first trail ride - she was never ridden anywhere but in her pasture before I got her. The only problem I had would not have been fixed by a bit - she got tired (she was carrying twice the weight the other horses were carrying - I'm hugely fat!) and she got a little pissy when she got tired. She was never "out of control," she just pawed the ground when asked to stand and wait for the other riders to finish practicing going across the teeter totter obstacle on the trail. Because of her breed/build, when she pawed, she had a LOT of knee action when she was pawing, and her nose was touching her chest - made it a little scary to those not familiar with her or the breeding. (Those of us who knew Dancer, and the background of the Spanish Mustangs weren't particularly impressed.) A bit wouldn't have fixed that. A quick smack on the neck sure did. That was the only bad moment she had on the trail.
Plain Old Dee, horses Dancer and Rain I believe in dragons, unicorns, good men and other mythical creatures!
