The forward facing ones in Cambridgeshire I think. I am in a daze when I drive down there (visiting the Mother in Law)and I can’t remember precisely. I do the run about 5 or 6 times a year in the car, but rarely on the bikes these days. One had a smilley face painted on it and another had been bent right back. This was about a month ago.
I use the A14 occasionally, which ones?
PS Nice link to the Gatso site. I went there before but couldn’t understand a word. Sorted now.
