270 miles via I-26, SC 6, SC 178, I-20 and US 441.
This was supposed to be a 256 mile hop, but we got embroiled in a battle between Google and our Rand McNally GPS. Usually when I plan a route with Google the GPS agrees with it, more or less. Not this time. When we got underway and made it to I-26, the GPS told us that we would be exiting after 43 miles while the Google route had us staying on I-26 for over 80 miles. We decided to stay on I-26. In retrospect, this was probably a mistake.
Even after we exited I-26, onto SC 6, the GPS continued to disagree with Google. We tried to follow the map directions but got confused somewhere along the line, then switched to the GPS which routed us on a very roundabout path to I-20. The net result was that the route became 14 miles longer than planned.
In a driving rain.
This was not one of the more enjoyable hops in our journeys.
Fortunately, the rain pretty much stopped before we did, so we set up in a light drizzle rather than a downpour.
