The interstate mentioned is I-285 or "the perimeter". This is why those of us who have lived in Atlanta and/or have to travel through often, urge RVer's to go straight through On I-75 or I-85. There is a total disregard for speed limits on the perimeter and it is full of 18 wheelers. It is very difficult for drivers who are unfamiliar with the lane changes to make split second decision about where they need to be. I had rather sit in standstill traffic for 1/2 an hour than subject myself to that. lizzie
