I really can't put my finger on it.
Maybe it's just because there aren't a lot (any) kids up there. It's mostly middle aged men from the neighborhood in the afternoons.
I think it's really interesting that he will go up there and play around on his own. He likes it that there's "no pressure and I can just work on some stuff and think about things and try to get better at it".
I do know that there is a counselor at school that Mo admires. Let's call him "Ben". Ben has really helped Mo think through some difficult things and learn how to think things through in a good way. Ben has been a very good influence on Mo.
Ben plays golf (not with Mo) but Mo is trying to convince him to put together a golf team.
I think that somehow that might be the spark that set Mo off.
But Mr. B plays a lot of golf too (and he has also been a very good influence on Mo (and he's Mo's usual golf partner)) and a couple of months ago he bought Mo a new set of clubs.
The new clubs seemed to invigorate Mo's interest in the sport.
