I've been hedging on trying out for our local team here for the past two years. Every time they post a try out, I contact them, then don't go. It's the time committment mostly for me, but I'm also concerned about the cost.
I wouldn't want to give up my normal skating, which is about once a week, so that would end up being either two evenings a week when I'm not home, or else one evening plus a weekend day. And it's not just the practice time - it's also the driving to and from the rink, which is over an hour from my home. I already have to drive that far to get to my normal lessons, I work full time, and taking additional time away from my family just isn't fair to them or to me - I want to see them occasionally, after all.
What attracts me is the comeraderie they seem to have on the team, as well as the fun of skating.
