OK, this was a fun trip through my photo archive. I'm actually surprised I have so many solo charging photos that fit this thread.
I agree with the thread's premise, that charging alone will be increasingly rare. Indeed, on my Nov/Dec 2018 trips from DC to NJ, nearly everywhere I stopped was full or nearly full.
August 2016 was part of a 1300-mile trip to Hershey PA, Cooperstown NY, Hartford CT, Boston MA, and Barnegat NJ.
August 2014 was part of a 2500-mile trip to Myrtle Beach SC, Savannah GA, Ft Lauderdale FL, and Charleston SC.
