Plotting Points-Latitude/Longitude

[berdan]

A trip to montana a while back got me interested in this sort of land nav. I bought a USGS map of the area we where in as a momento. Since MGRS is the only way of plotting points I was familiar with it got me to wondering how I could go about plotting cooridinates onto the map if it only had LAT/LONG markings. Had a gps at the time so I new the location of where we were but did not know how to plot the LAT/LONG from the GPS to the map, or plot where we wanted to go on the map and then punch it in the GPS. I thought this would be a neet trick to learn if I ever had to use any maps that did not use MGRS.

Here is what I found.

Would this sort if info have any use? Have any of you found it neccessary to use foriegn maps that only had LAT/LONG? How handy do you think this trick could be?
