What struck my tire looked like a metal part from an umbrella. It had a "v" cross-section which made the air go out instantly. I have read a lot (too much) about similar incidents at C5, and I'm sure this is man-made. Be careful guys and gals, and never stop at the dark spots.
Thanks for the warning. Pass by there occassionally as well.
