Simply beautiful photos! My personal favorite is from the campus of the College of Charleston. Charleston is one of my favorite cities, yet I have never visited the campus.
Since you visited both the Varsity and Beacon Drive-Ins, I believe you have hit the two largest drive-ins in the country. Personally, I prefer the Beacon and it has everything to do with how well you are treated there.
Thanks for sharing the excellent report!
Do you have friends in every city?
