Oh, yeah...I expect these will leave some marks that last a while. I did a snowy cyclocross race back in mid-Feb. There was one stretch where I was trying to get around a kid who was weaving all over...and of course he wove towards me as I did so, forcing me into a tree. That left a knot on my shin that only seems to have disappeared completely maybe in the past few weeks. I still have a shadow of a hematoma I got last Fall mountain biking, too.

As a teenager I was thrown from a snowmobile onto an icy lake (my friend piloting the snowmobile lost control on the ice and the 2 of us went flying as the snowmobile flipped onto its side--I'm just thankful my leg didn't end up under it) and that hematoma on my hip left a shadow for at least a year. That was fun, since I was a cheerleader and every time I'd do a round-off the world got to see my dinner plate-sized bruise!
