Wow, that would have been a tough ticket to get.I mainly use maps for checking private property. I then resort to a GPS for my location if I am getting close. A few years ago I found that I had been hunting on Reservation land that wasn't marked on a map. I found this out by using a GPS and OnX. I also notified some other hunters who were camping on it. The funny thing was that these hunters were hiking into private property in Colorado from Utah to hunt with Utah tags, bad on all counts. They had no idea of where they really were.
