Roads near Marietta Georgia?

The Marietta Georgia area where my grandparents live seems has so much more roads than Tuscalossa AL. Any routes that people in Georgia like to do? My grandparents specifically live down the road from Pigeon Hill, close to the Kennesaw mountain area.

While y'all are at it any roads near AL would be nice. I live in the Tuscaloosa/Northport area near downtown, close to UA.
