My name is Jonathan Karpoff and I teach at the University of Washington. I stumbled on the trails out of the Fish Lake Sno-Park years ago when I was looking for some new skiing territory. I've skied ski and snowmobile trails wherever I can, but keep coming back to Fish Lake for its proximity to Seattle, wonderful scenery, and solitude (at least in the morning).
A few years ago some snowmobilers I saw during a break on the trail (it was a long day and I was not following ASS Rule #1) said, "So you're The Skier!" I've heard that a few times since. As a nickname, that's a keeper.
Nowadays there are other skiers out there. Not too many, and you are unlikely to see anyone else on an ASS ski, as long as you follow ASS Rule #1 (see the rules). But you might just find the tell-tale Y-shaped tracks of another skier or two as you return to the Sno-park from a heart-thumping ski.
See the Trail Guide to see what you are in for if you try some ASS.
