I had 3 flats on what most locals call the dam loop. I now call it the Damn Loop. It goes along the lake, where there is a lot of new house construction. The first flat was from a roof staple, the second was a finishing nail, the third was a pinch flat because all I had left was a 12g Walmart CO2 cartridge, which I couldn't get to totally fill the tire. I have had a flat almost every time I took that route. I don't do it anymore.
