We have used My Dad and Me Farm in Powder Springs - (
http://www.localharvest.org/farms/M22878). It is very nice, raw milk, fresh eggs, sometimes fresh chickens, raw honey, raspberry and blueberry bushes, and other fresh produce. They have raised their milk price to $10/gallon (use 1/2 gallon glass jars) and now have a $25 yearly membership fee. You can schedule to pick-up your milk anyday during normal business hours.
We now use Carlton Farms (
http://www.carltonfarm.com/) because he's closer and cheaper. His raw milk is $7/gallon in plastic gallon jugs. He brings milk, eggs, raw cheese, raw honey, and sometimes CSA produce boxes to several locations around Atlanta. He has a delivery location at Mt Paran North Church of God - 1700 Allgood Rd. Marietta, GA 30062 on Thursdays from 2:30-3:30.
