holy cow I was there the exact same time (Feb '06). we drove up to Q City, then rode from there up to Jonquiere. then around lac St Jean and by Mt Valin. it was a very fun trip, but super cold. we were all dressed for it and were fine. lots of stops at the remote "relais" to warm up.
One thing i do remember quite well is one of my buddies on a Yamaha, that had the exhaust out the back by the tail light. we got to an intersection and he was stopped, and I thought his sled was on fire-but it was just the exhaust.
