I have recently started using Travel Management Maps for trip planning. These have started becoming available over the past year or so. At first the idea of using these was repugnant to me on the general principle of being strongly opposed to land closures. But I broke down and started checking them to see if the roads I wanted to ride were actually open. I found these maps often show roads that don't appear on any other digital or paper map I have. You have to search online for the particular forest or BLM district you are interested in. In a few cases I have done a screen capture of a map and then imported it into Google Earth and georeferenced it to create a kmz file. I then load the kmz file into Basecamp and manually draw tracks in areas where my other maps don't show roads. I understand that all of the Colorado National Forest MVUM maps are available as kmz files.
