We are going down to Atlanta for a Monster Truck show at the Dome. We are thinking about staying in Sandy Springs and riding the MARTA down early that afternoon and using it after the show which will be around 10ish. We have two small children (4&5) and we are wondering if this is safe? I know going down will be fine, but I am concerned about the trip back. Any suggestions? I know going back we will have to change trains before Sandy Springs because of the time.
