GA Coverage Area

[sjcruiser36]

I'm flying into Atlanta tomorrow afternoon and driving about 2 hours south/southeast to Davisboro to see family until Monday. I'll be driving back to Atlanta to fly back to South Jersey. I normally do the 12 hour drive down, but just can't take it anymore. When driving, I get signal until I'm just outside Augusta and don't get a signal until I'm driving back through Augusta. I haven't been down there for a year. Anyone know if Sprint has added any towers in the 31018 area of Georgia? The only answer I can get from them is to check the coverage map and roaming area.
