Seen most of them apart from castleford, catalan and Rovers
The rest i have seen numerous times,
i think the rhinos truck is top of the list for seeing the most.
The main area i have seen them is on the A1 south of Doncaster down towards peterborough.
the furthest south i have seen one is on the M25 near Thurrock.
Just off to take my anorak off now
