Sometimes you just have to battle it out. We have pulled down sleds out of plenty of deep valleys over the years. I now have a block and tackle, along with hundreds of feet of rope that I keep in my truck. Beyond that, we have literally pulled sleds foot by foot by hand for hours to get them out to a tow-able location. Just part of what you should be ready to deal with if you are riding in areas without poor access. In the U.P. you have two two options, Fix it, or pull it. You would be amazed what you can make happen with 3 guys, time and patience. A good block and tackle, with hundreds of feet of rope, and you are virtually unstoppable.
