Drawing pins.

[StuartG]

I'm wary of repeating the wire/rope incidents publicly in that it could give other toss-pots ideas. Originality is probably not their thing.

There's been a few reports in Wales.

Lots of tacks on the Swansea Mumbles cycle track.

Even the former Welsh Secretary was filmed sabotaging a mountain bike track in the woods.

I thought he was more interested in "badgers"?

He get's up to lots of things in woods apparently.
All well documented in the south Wales press.

I've seen a few ropes across paths when I was on the TPT through Wombwell.

Schwalbe marathon plus tyres can withstand drawing pins.

FWIW, I had a tack go through the Marathon on the front of the Brompton a few months back. They're good, but sometimes you hit something at just the right(wrong) angle.

Legitimate 4x4 drivers on green lanes are being targeted of late by the old nails through the board trick. That's not very clever, as if the 4x4 lot catch them they'd quite likely end up in an unmarked grave!

A combination of choice of font, old eyes and early morning blearyness made that read like "unmarked gravel", which still made sense (more or less).
