It was a muddy ride. But she was still happy :)

I know a lot of my followers are horse people. I have a 15yr old paint mare, very good shape and has no health problems. she has a very old style ranch horse kind of build. I am trying to find a “job” for her that fits well. Problem is, she’s barely cowey, could do western pleasure but hates it and is not really nimble enough for reining. I am in a rodeo drill team during the summer which she loves, she loves to run and had endless energy but is willing to do anything you ask, or at least try. Any ideas? I’m kind of stuck.
