Floating fence next to the tree tunnel

When riding the island counter-clockwise the row of tree stumps immediately on the far side of the tunnel through the tree appear to be floating about 4 feet off the ground.

I noticed this in both the Windows and Mac versions.

How do you ride the course counter-clockwise?

I saw that too recently. Also saw a black bear for the first time last night. A rider had stopped next to it and the bear was standing up like it was getting ready to eat the guy!
