I do this all the time. My Etrex Vista will hold about 20 Mb of maps, so I can load most of where I am going to be. If I had more memory, I would just load all of CO, WY, UT, MT. The MapSource program allows you to select regions of a map to transfer to the GPS. You can also mark waypoints on the maps, and store those. This can be very handy when you are traveling in new areas, and are looking for public land boundaries, BLM, boat ramps.
On the trail, you can mark various locations, and then send them back to your computer for storage.
