Pick-up or putt?

I think it is fun that people use our local parks for so many different things. On my morning walks, I see people stretching and working with personal trainers. Some people come to have picnics and birthday parties. Recently I came across this man golfing (or at least putting).

Of course, there is the pick-up game crowd too. Although I missed most of the action, they looked like they had had a good workout.
