I made a trip out and about today and stopped by Cabela's located at
152 Northpoint Parkway, Acworth, GA 30102. (MP 277, I-75 and Ga. Hwy 92) This can easily be seen from I-75. There were signs leading to "Truck and RV Parking", so we checked it out. There are only about 5 spaces in the back of the store, nothing special and no hook-ups, but they do have a dump station!
(For customer use only) I just thought this might be useful information for snowbirds and other birds as they travel along I-75.
