i played a lot of roller hockey growing up, started play some ice in college. played in a men's league and then some pickup. a couple years ago i stumbled on a roller hockey game on the hill. there was a pretty varied mix of skill levels. then we started advertising on meetup.com (look for capitol hill inline league) and the skill level has started to skew higher, but is still pretty varied.
basically play sunday mornings, no longer on the hill. there are a couple rinks in MD off 295. all the details are on that website.
i like ice hockey better, but am starting to prefer the roller hockey experience. get to play outside. if it is cold, you can kind of pretend it is pond hockey. no crazy hours. tomorrow should be nice (30's and sunny).
we usually have two full lines and goalies. even with the high skill level, it is very friendly. wide range of ages. most people are at least 30. maybe some are even 60. so its not like there are punk kids playing.
due to the fact it is ball hockey, the skill level is higher than the A/B league I've played in. its just easier to play with a ball
its not even a league. no fees. just show up. really cant be beat
