This trail will definitely imporve your skill with its massive jumps and a nice creek bed to go down. Dont take any turn offs until you do down the first real down hill and run into THE jump. Its broken bone counter in at nine right now. Once you get the jump, do it, its all in you head. Go anyway you want, but before you leave, make sure to do the bridge. There are jumps spread all around the trail, do as many as you can handle.
One more thing, it gets pretty busy during the weekend, so you should do it after work if you can. I myself ride it after school sometimes.
How to get there:
Take 400 N from ATL and exit right on exit 8. Then, go right into the WOODSIDE OFFICE PARK. Take the first right into the parking lot and head towards the back right corner and you will pick up the trail.
