Day two with M.E.S.A. was a blast. It was just the five year old and I, since the 10 year old had air rifle practice. The two year old stayed with Bugga again - although he begged and begged to get to go see the horses. He'll get his chance later, once the five year old settles in.
O, by the way, we learned that a horse that has white over it's main color is called roan. I think I'm going to start using that personally. Sounds much better than "greying." ;)
