Before I purchased a purpose built sled I used a large plastic drum cut in half length ways. It must be the type with the molded lid, not the screw type.
Simple drill two holes for the rope to go through one end and then either attach it to your harness or just drag by hand. This simple idea can get you out of a lot of problems especially at last light, when you are on your own and some distance from your vehicle. It costs virtually nothing to make. You could always leave a couple hidden at each end of your wood if you spray them suitable.
