I did use the grapevine and the smoke smelled almost incense-like. (it was a nice smell) Apparently I didn't use enough to make a difference tho.

The actual Rollerblading incident happened in Breakheart. I was by myself, swooshing in gentle "s" like curves as if I was skiing when all of a sudden I was on the fast track to doom. Long downhill, No shoulder on the road, vertical rock on one side and guardrail and a drop on the other side. I chose the 12" of dirt in front of the rock. This allowed me to instantly convert from skating to running, but not for long. The dirt lane ran out and became road again, my feet went out from under me and I hit the ground like 'a sack of potatoes'.
