Still in UK on a rainy day - still in PJs also!
But it didn't stop me going out for a drive: and just realised that one more suble difference between our nations is the red/yellow traffic light combination!
Guess every one knows that red is for stop and green for go (except in Boston)...

Red and yellow in the US means definitely stop (?) (pedestrian or policeman has control over the lights)
Red and yellow in the UK means definitely start (the lights will go green in the next second)
I am just glad that we drive on the other side of the road - it seems to be the only thing that make the foreigners drive sensibly when in the commonwealth.

God help the traffic lights
