Disc golf is the sport for nerdy kids who never liked sports. And even if you're absolutely terrible, you get to take a nice walk in the park or the woods. Most courses are free to play, and you really only need one disc to have a good time. Strongly recommend for those who know they aren't active enough but have no interest in going to the gym.
You gotta be careful though. My best friend tried to take a girl out on a discgolf date once. She said "no thanks discgolf is a gateway drug to marijuana. " and she might be right.
