When I was in the North Carolina I was looking for all back roads and no interstates. My GPS found me some great roads. I stopped at a state sponsored rest stop and it had a lot of information about the Blue Ridge Parkway and figured that would be great. I punched it in and my GPS took me into a neighborhood and up a steep hill and the road turned to dirt. I figured it was a great road for a 4x4 but it sucked for my 911. I stopped and turned around, when back to the highway and the GPS was trying to reroute me right back up that hill. Within a mile there was a big sign pointing to the parkway. I went that way and I was on the parkway before my GPS decided that would be a good route.
I took my favorite picture of my 911 that day.
