MTB on the bike paths with Mary. We went over to the YSI fields , met Sandy, and watched some of the frisbee dog competition. Mary's co-worker is part of the KC frisbee dog group and they had a big tent we could use to get out of the sun while we watched. She also explained the scoring/judging system for the event we were watching (dog athletic ability, catch/drop ratio, something that I can't remember, and "wow factor.").
It was windy and that caused more missed frisbees than you'd have with a calmer day.
