Welcome to Bream Lake. This area is off limits to all motorized vehicles, so you will have to hike back and around the lake. You can park off of Hwy 40 by the gate, just don't block it. This cache is along the trail that will take you down to Bream Lake. The locals have made their way around the gate and created a road down to the lake, but as mentioned, this entire area is off limits to motorized vehicles. If you drove back here anyway and get caught, you will have to deal with the consequenses yourself.
You will have to do some bushwacking to get to this one. Look for the 6'-7' myrtles South of the trail, past the palmetto patch. Please try to place this cache back as you found it so it's not visible from the trail.
