Historical Topographic Maps
Of course, most GPSr's back then did not have built-in background maps, so we still had to rely more heavily on the beloved USGS TOPO map to keep ourselves from getting lost. As such, many of us have acquired quite a collection of TOPO maps over the year, myself included.
If you grew up with a, some might call it sick, fondness for TOPO maps, then you might be interested to know that the USGS is converting all of their historical printed topographic quadrangles to an electronic format and making them available for download. This will be a great way to see how much has changed in your area of interest over the years, if at all, as these maps include such wonderful detail. I know I'm looking forward to seeing the railroad alignment that used to run through my neck of the woods long before I arrived here. There is no longer any physical evidence that it ever existed. The only clue I've had up until now, ironically, is from a geocache: Eastport.
