I would be very surprised if there were no COEs at this place. It is located just south of Hiram on Hwy 92. From Marietta you can either take the 120 loop or Macland Road westward until you reach Hwy 92 (about 10-15 minutes). Then turn south on 92 and once you reach the Hwy 278/92 intersection continue for ten more minutes and the yard will be on the left. It's in very clear view. There is nothing else around it. It's called "Alsobrooks Garage"; number is 770-943-3490. The owner's name is George.
