I've been looking at the best way to get to the staging area. The Casto Trading Parking lot is really small. So is Statham, but it can get crowded.
If coming in on Ga. 316, University Parkway, exit left onto Hwy 211 at the sign that points to Statham. This is Bethlehem Road. Don't confuse it with Carl-Bethlehem Road, which is also Hwy 211.
At the end you will see the railroad in front of you. Turn left, go to the first crossing on the right (Mulberry Street) turn right and immediately right again onto Railroad Street. This runs along the other side of the railroad and leads directly into the Casto Trading parking lot.
If coming out of Winder on Atlanta Hwy, follow alongside the railroad and as you near Statham there will be Statham Storage on the right. Take the first RR crossing to the left onto Mulberry Street then immediately right onto Railroad Street and follow to the Casto Trading parking lot.
