Had an early morning ride at Frith Hill this am, and suffered not one but 3 punctures. No story there apart from all 3 were caused by drawing pins; 2 in the front no more than an inch or two apart, one in the back. Apart from the fact that all 3 looked pretty new and shiny, to get two in one tyre so close to each other in the tyre, it is imho beyond coincidence to think you'd get one and then another right next to it later.
I think someone's out there acting silly, so take spare tubes and watch out.
If you know the area, I did a loop of the Gorrick course and the punctures were sustained somewhere on the section near the longish drag to the corner by the house on the private road through the twisty ditchy singletrack in the trees on the left that follows it, as the flats became noticeable on the gravelly climb after that.
