sometimes if brigades are pretty strict on trainings that members must attend, then footy twice a week, plus cfs, plus for me staff meetings once or twice a week, plus all the after hours stuff teachers are expected to do gets a bit much, and a decision needs to be made as to what gives. (When my knee gave, that was pretty easy option for no footy...)
But def in country areas you tend to get involved in stuff, so as to not be considered a hermit...
