Best mapping software out there. I still use it too. To complement my GPS. I have it on my laptop, and I also print maps and directions when making a trip. I will use these if I don't like what my GPS is trying to make me do. Then the GPS has to recalculate according to my wishes.
Many years ago, when stationed at Ft Knox, some of us did a lot of 'Spelunking'. We had detailed maps (Corps of Engineers or Coast and Geodetic Survey Maps) which located many wild caves in Kentucky. We visited many of them with flashlights and carbide lamps.
Maybe it was my training to navigate without even a compass that I can almost instantly know where north is, night or day. It still astounds me with the infinite amount of variables that Polaris is what it is. Divine.
