First week in Feb. '94 I think. It was warm all week, but we made the trip up to Minocqua for the weekend after a local buisness informed us that the snow was holding up. When we got to the cottage, there was enough snow to ride on, and rode across the Willow Flowage. That was a big mistake, it was 2' of slushy water on top, and it started to rain. We sat at a bar and waited for the rain to stop. It rained hard for 4 hours. The Willow Flowage looked like a lake in the summer time. We had no choice but to return trip around the flowage on nothing but ice and mud. It was about a 30 mile trip, one sled went sideways on a stretch of ice on a road, then hit gravel and flipped on its "shiny side", and rider sliding on his back on the gravel for 40 yards. We finally made it back to the cottage in time for breakfast and loaded up for home. We had some parts to replace, but we had plenty of time to do that, since the trails didn't open any more that year. One of those trips we will never forget, but wish we could.
