Actually the sport was a rowing/crew. Lots of high school teams were there, it involved racing, time-trials, etc. The parent in question has a preference for the usual team sports, basketball, football, etc. I wanted to expose the den to a sport that was relevant to the region I live in, is actually a challenging TEAM sport and requires planning and real effort to be successful. Not unlike the other "traditional" sports.
I got some really good feedback from the other parents, the kids had fun, and everyone learned something new. The cubmaster and all the leadership has been supportive
