The way to do it is two ride on the sled carrying boards/skiis. The lower part of Gold Creek looks bad but thats how all the trails are this time of year as they no longer groom. I am sure it would be better at Crystal Springs. There are some good areas to ride ski by the radio tower, about 10 miles in. I went to French Cabin Creek (Cooper Pass end of Lake Cle Elum) this weekend and it was great, the snow up high is still great and lots of it. I just rode the sled as that was fun enough, lots of good hills and open areas to ride off the trails. I would not tow someone up, thats a tough way to do it. What do you have for a sled?
heres a pic I took up by Cooper Pass on Saturday, lots of snow;
