Cruzilla...
just got back from Dusy and Swamp lake two weeks ago, had a great time.
Dusy is one of my favorite trails, not due to the technical aspect of the wheeling (which is good) but the geographic area and high country wheeling... it's absolutely gorgeous up there.
We also ran Swamp lake for the first time and although I had heard stories the trail was pretty tame, we enjoyed it immensely and thought the wheeling was great. Oh, and Swamp lake has got to be the most inappropriately named lake around, there was nothing swampy about it!
have a great time...
