That photo was taken in 2004 on my Appalachian Trail thru-hike when Buddy and I stopped into the DWG visitor's center. I vaguely remember a photographer following me around there, but had no idea this 7 year old photo even existed let alone was being used in the banner on their website.

And I promise more posts are coming soon! Happy Hiking!
