Sure, not superstitious about things like this. If it was a friend or loved one I would do so to honor them. If a stranger, it would be more of a neutral, but I might think of it as an honor to a fallen comrade.
My thoughts exactly! When I die, I want one of my riding buddies to take my board out for some runs. Only on the powder and steeps though! I'd do the same for a fallen friend.
