"the Plod in the UK and USA are now actively asking all 'spotters' to log any suspicious looking vehicles"
With my spotters head on, Manchester Airport (aka Ringway to the older chaps) now known as the best spotters venue in the UK (they actually positively encourage people to visit) have recently had a police poster put up so locals can help. Shame the rest of the country doesn,t have the same approach.
