Nothing quite like riding in "certain areas" and hear a bike tube explode. The First thing your brain thinks is gun shot! Then you have to calm your heart down when you realize that it's *only* a bike tube. Meanwhile you're still mentally doing the body check for new holes.

Last year on the MS ride, day two, after about 2 miles several people had blow outs - blam! blam! blam! Made us think we were in a shooting range.
