Sports for Teen Boy

[Eliza5]

I'm finding it hard to find sports activities for my 14 year old boy - they all seem to be geared towards age 4-12 or adult, and not much in between. 

He is particularly interested in hockey or a local gym that he could join without a parent having to become a member, but we will consider other sports ideas as well.  We don't have a car so it has to be local or accessible by subway.
