I am curious where most folks get their maps for 'field use'. Do you use the seven and a half minute, 1:24,000 scale topo's that the Geological survey produces. Or do you create your own by one of the various computer mapping programs.

I'm also curious what grid format most folks are more comfortable with...UTM or degrees and decimal minutes.

And last, If you use a G.P.S. with your map, where did you learn how to interpret grid coordinates...From a book, video, or did someone show you how.

Thanks in advance.
