Watch for squirrel traps. These hidden little divots under the leaves where the squirrels have dug up their acorns are impossible to see. Take care of your ankles.

On windy days listen closely to the trees. One of them just might call out "That's all I got." and come crashing down.

When approaching a obstacle on a muddy path, make sure you know how your foot is going to land of the other side. Mud and leaves can send your lead foot in a wrong direction fast.
