Spotters on the M6 junct 9

Just before the slip for 9 on the northbound there is this concrete walk-way:

Those guys who stand there with duffle coats and notebooks, they´re spotters, right? I thought they were Stobbie stalkers, but the other day they, as I inched forward in traffic, I swear one of them looked straight at my trolley and wrote something in his notebook. Weird.

They can double up on the train and truck spotting there.

they always take a picture of my truck. they sometimes get a bit excited.
but i can’t find many pictures on tinterweb.

funnily enough I have not long come through there, a few spotters up there with their cameras taking a picture of me coming through, was a bit different!
