The path is in blue and was taken with my GPS and imported into Google Earth. Atlanta is off the map to the South West. We put in at 10:50am, stopped once for lunch and took out at 4:20pm.
We were not in a hurry. The trip was between 13 and 14 miles.
That water was COLD!! It was 50F! The signs at the put-in talked a lot about hypothermia if we were in the water. The signs all said NO SWIMMING because of that.
As an added bonus, there were mile markers most of the way to Abbotts Bridge. It was a game to take a picture of each one. The first one was in some rapids so I missed it.
