Live Google map
The blue track shows the February 2011 route. It was made with a Magellan eXplorist 500, which often got confused, so where the tracks differ only slightly, one should probably believe the red, November 2012, track, made with a Magellan eXplorist 310, which seems to usually be a bit more accurate.
One major difference is toward the top, left-center, where previously we visited the lower bunker but not this time due to "Private Property" postings.
I tried out most of the other map settings (pull-down menu upper right); I wonder what "Blue Marble" is supposed to be?
