Yesterday I had the [dis]pleasure of leaving the greater London area. Unfortunately, my train to Cambridge was re-routed via bus through the lovely hamlets of Letchworth Garden "City", Royston and Stevenage. I didn't see any imps directly, but I did some sniffing around to see what might turn up.
The oldest roundabout in the UK (established 1909) was fortunately on our route, and - let me tell you - it certainly was still in operation. It provided the road with traffic control system that was both smartly landscaped and ergonomic. Seeing how many Britons flock down the route between Stevenage and Letchworth on a daily basis, i'm sure glad that roundabout was there.
Of course, there was an abandoned factory in the Royston indsustrial park that must have been teaming with impsies. Keep a close watch on this area for future sightings. I daresay I won't be going back that way for a while though.
