I just feel like if he was down there for several days, he surely encountered someone. With so few visitors this time of year, I hope he stood out to someone - maybe in a gas station or grocery store. Per one of the N.C. DOT pages, there are 18 traffic cams (if I counted them correctly) on Hwy 12 from Point Harbor to Hatteras. Hopefully they can pinpoint exact times and locations from those and create a more accurate timeline. There are also cams on both the north and south docks for the Hatteras/Ocracoke ferry.
Since Virginia uses front and back license plates, I’m also wondering if maybe a better photo was captured at the toll plaza on the Chesapeake Expressway.
