Brits in an RV - Denver to San Francisco

When I toured the British Isles in the early 80s, I found that driving from the right seat in the left lane required an extra amount of alertness. Roundabouts were a new experience. Some cities here have them now. I also found out that when you hear a horn, something bad is about to happen. On this side of the Atlantic, we also use them for doorbells and for waving to somebody. But most important, if you walk across a street between intersections, the traffic in the closest lane is coming from the left. That's when you pay attention to a horn. :)
Hope you have a wonderful visit.
