Tip Macadam. - FotheringtonThomas
Coming out of the council's tip (AKA recycling depot) I noticed some shiny new woodscrews ahead on the short spur off the main road. Hah! thought I, I'll stop and remove them. So, after a few people had overtaken (thereby driving through the puddle of screws on the road) I did. There were quite a number!

Quite an interesting road surface, there. There are bits of old pipe, wire, nails, screws and so forth, all pressed into the surface of the tarmac, so many indeed that it looks like an agglomerate of sharp bits of metal and tar.

I wonder how many punctures result from trips to tips?

A very good point(groan), never considered that. I'll save my ventures to the tip for when I get a courtesy car ;-)
