Right, it was a mile or so to the headwaters of the creeks, and then all downhill from there. Back yard: Lullwater Creek>Peavine Creek>Peachtree Creek>Chattahoochee River>Apalachicola River>Gulf of Mexico
Across the street: Sugar Creek>South River>Ocmulgee River>Altamaha River>Atlantic Ocean

My house in Atlanta was on the eastern continental divide. When you click on my back yard it flows to the Gulf and when you click across the street it flows to the Atlantic.
