While camping at our family reunion I heard this tock tock tock noise....kinda like in the movie where the Blair Witch was hitting rocks together. Feeling like I had to protect my family, I went to get the only defense I found, (my nephew's new Red Ryder bb gun) and went looking.

To my disappointment, I found the gazebo we had set up had flipped in the wind and was stuck between the cars. The poles were hitting them making that scary sound.
Dang. What a let down.
