Mystery Man (his name starts with AJ)

I purposefully blurred the individual skating in these photos to protect his identity. I don't want him, you, or anyone else to be hurt from backside noseblunts down rails, so I won't risk it by letting you know who it is. If you can even make a guess as to what I'm talking about, then you are truly inspired. But if not, then join the club. Anyway, AJ can do backside noseblunts, can you? I can't...
