Thanks all for your reply,
There all good, but surf might be a problem around Montreal as the only wawe you will see here are at a hockey game
As far as staying in shape, I'm triyng to keep pretty fit (at 35, with a daugther, a day job and way too many passions, it a survival requirement).
My point was more about doing stuff that will help me out with the riding aspect (stance, heel and toe action, transition, etc.) so I guess at this point skate and balance board might be my best bet.
