Hey Guy,
I take it you mean Interstate 20.
You'll be going right through Atlanta and the most populated area of Georgia.
VHF will keep you slammin' with everything under the sun. Just let your radio scan from 145.200 ~ 174.000mhz. You'll hear everything including the kitchen sink.
And there's always CB freq's for the whole trip
Happy drivin' & listenin'
Be sure to stop at Sam's Beaver Burgers & Bar B Que Barn. Look for the big tail on the billboards.
