would not suprise me if it was part of the highways people.
its the start of the month and they sit in just that sort of place to catch people that have not renewed their car tax.
sneeky but thats the way these people do things these days.

take the picture to your local mp and ask what is this car filming in foresthill, they should know just going by the number on the van,
but i do think its number plate reading on the passing traffic.

what a shame he did not park outside the bird in hand , he could then catch all the people going past the do no enter sign.
