Make sure you follow the path exactly as laid out, or you won't be able make it to the end.
The Road Closed Barrier is the trail head and the begin of your journey. To find the starting point, go right at the second path (just past the trail post) You'll have to walk a little ways before seeing the first fire tack. And remember, stay on the paths until you reach the tree with five fire tacks..
You'll see different amounts along the trail. But make sure you walk slowly and scan both sides so you don't miss any. They will always be in front of you and show the way.
When you see 2 you need to go RIGHT When you see 3 your need to go LEFT
When you get to the tree with five fire tacks walk past it and follow the tacks SE to a large tree that shows the way to GZ. X marks the spot.
