just a word of caution from an old timer? gesticulating at drivers, slapping cars, pointing cameras, even if perfectly justified, is not without hazard. I did something very similar to sjb a couple of weeks ago. The car driver threw a U turn in front of fast on-coming traffic, mounted the kerb and out got 2 very large thugs of Eastern European appearance. I just managed to leg it across the road and into a park - a bit of a chase followed with them hurling things, and I have no doubt that they would have done real violence had they caught up

. There are some serious nutters out there so don't put yourself in danger, it ain't worth it.
