Spotted...

That was indeed me. ..picked up a pair of tyres on my way home. ¡Hola!

There were a couple of pinch points and a closed lane ahead plus a nasty furrow in the tarmac that is slippery when wet. ..was quite happy to sit back and take a tow off that HGV instead of over/undertaking it. Besides, I've got a bad track record for filtering with tyres on my back! :D

I'll give you a toot next time (I was in the white van). Got to say I rarely see such responsible riding down that road.
