Someone can probably look at the gas price signs and make a better guess at exactly when Socastee Mini Mart went under, but I'm pretty sure it was open last summer and not last November 13th (when these pictures were taken -- Unfortunately, it was not a sunny day).
The place is on SC-544, probably 5 miles on the Socastee side of Coastal Carolina. SC-544 is the handy little cut-through from US-501 to US-17 and can save you a lot of grief if you end up inbound to Myrtle by the north route. It's less useful than it used to be though, as there are now more lights and a constant 45MPH speed limit. For many years, the road had a real rural character, and this station is a holdover from that era. Now however the area is getting more and more built up, and "regular" chains are starting to move in.
