I have been looking at my OnX application here quite a bit lately for route planning and topos for next fall's hunting trips and it occurred to me it would be perfect for Boondock Camping. OnX gives you the Sat image, topo image and a hybrid mix of the two. Plus it functions better for me than GPS when you are out hiking, even if out of cell range by screen capturing your map image from cell service and then putting the GPS location overlay on it to use when you are out of cell range. Neat, not cheap around $100 for the entire US but I think an individual state is about $30. Its on the internet, I think it lets you use it free too, but I am not sure right now. For my simian brain it beats a hand held GPS for about everything except for active airplane pilots and nuclear weapon targeting stuff. As long as I have smartphone phone battery I shouldn't get lost any time soon. But never say never!
