Sweep snow off their vehicles on the way to practice?
The boys are going to either own or rent a place with a garage, they can afford that even with even entry level contracts. I would guess most have heated/climate controlled garages as well....at least I would.
I can't speak for the practice facilities, if they have indoor parking...but I imagine there would be for most NHL teams, because the inverse is true as well...Could you imagine going out to your Audi R8/BMW M6 that is sitting in the parking lot in the southern states heat?
