Re: National Geographic Topo Question

As amazingly easy as MGRS (UTM, basically) is, people still mess it up. Guys trying out for Army SF have been known to walk a back azimuth when trying to dead reckon. One thing I've noticed with navigation, is it's hard to let go of the way you're first taught. I'd imagine Big Sky was taught in the military, or by military.

Bill, I've used MGRS (and terrain association, of course) to find a person sleeping on the ground from over 15k away, as well as to navigate over entire countries. I'm sure you know about its flaws a lot more than I do, but I've never found its use to be limited to small areas.
