Oh Ya I've got three or four of them kicking around, I don't go into the woods without one, with DeLorme's Topo North America its right on your desktop, you can mark waypoints and routes, put down destinations, get latitude and longitude with a click of the mouse, its very convenient, something to mess with in the long winter months.
