The Piggly Wiggly was somewhere between Goodletsville and I-40. I can’t remember the exact town. This was in 2012.
One thing you have that we don’t have up here, Wal Mart has a liquor section.
You also had Mellow Yellow (Coke’s version of Mountain Dew), which us Yankees wouldn’t have for another few years.
There is a Waffle House in Bethlehem, PA (probably as far north as they get), but it’s still over an hour drive from here.
