Glad to hear you got Twist out, first time right? Did she go with other kids at the barn? How fun. My daughter has only trail ridden a handful of times but she LOVES it. As a matter of fact we went yesterday and the day before (I even trailered!). Lily has limited trail experience, as in almost none, and every now and then will stop, look and snort but Anna can get her past anything. The last couple of days I am on foot and Anna rides - not the optimal set up but she loves it nonetheless. She'll go ahead at a trot or canter and then come back to me and then go out again, etc.. She definitely prefers to go with other riders but a walking mom will do in a pinch.
Well, if Anna was with kids just learning to lope, or new at it, she would not enjoy it nearly as much. Anna is a pretty advanced rider for her age. On the other hand we don't do much ground work other than showmanship (but not much) and taking the horse out for walks - we've never done Clinton Anderson work.
