Boys are on a hike today. If son #1 completes a few more things, he will earn First Class before summer camp (#3, he's 13). Son #2 completed the Swimming merit badge. We are encouraging them to log for Personal Fitness over summer vacation.
I don't think many parents realize that we take gym 4-5 days a week usually, depending on where you go to school. Your son could easily track their activties from school, especially the warms ups that they should be doing daily during gym.
