A rail jam would be so cool.  Aight, I was watching fuel network one day and they had this documentary thing of a rail jam outside, in the parking lot of a snowboard shop in LA.  Try to talk to the D structure people and see if you could build scafolding in the parking lot, or use a hill nearby(I haven't ever been to Quebec or that area, so I don't know what it's like), and build a down kink or something.  You could make snow, haul in snow from resorts/ice rinks, or use snow around there.  If you got it to be at d struture, and them to be a sonsor, it would be dope.  I'm sure you could get some pro skiers if you did it that way.   Good luck.
