As Fall is now upon us and Halloween is just around the corner, beware of the wicked walnuts! By that I mean walnuts have fallen all over the trail, especially along the C&O. They are often obscured by fallen leaves. For those riding narrow tires, the walnuts present a danger of losing control if hit head on with the front wheel. I saw one rider go down hard as a result.
Be careful when riding through these areas.
