Do you ride in North Wales ? want to know the Mobile camera locations ?
 

Found this site, I don't know if it's been posted on here bofre. Go to schedule, and that will show where the vans will be.

Be warned, this is only a guide, in reality the buggers are never where they are supposed to be and when.
Its handy though for the favorite hotspots, but they are also getting very keen as you enter ruthin near brynhfyrdd school just as you enter the 30, you wont see then but they will see you, as they are parked in the school car park behind a couple of cars.

In all honesty its not so bad over there, just avoid sunny sundays and dont ride in large groups, our favourite is sat eve's or after work in the week, not a plod to be seen anywhere
