I bought a GPS thinking it would tell me all sorts of info and well it dose just not what i want to know, but I know have the ability to plot cord. from maps for state and BLM into my GPS. Using Maptools they are the greates things
you can buy them from John@ www.maptools.com please let him know you heard it from David in Montana.
if you need help with them let me know I have a guide book that I made to help other sportsman use the GPS to the fullest along with Mapsource and google earth. this info will help out any hunter were permission is getting hard to find
