On vacation in Oregon I think we were at Diamond Lake (near Crater lake.) which has a 20+ mile 2 lane paved bike path around it. So we're riding on the path, come around a sharp corner and there's a couple riding two abreast on the wrong side of the path. Quick braking, followed by some words i did not know I knew along the lines of "you morons, what are you, British? Get on the right side of the path..."

As we left I heard the woman in a serious and authentic British accent say "oh my, do they ride their bicycles on the right side of the road as well then?"

I'll take traffic over bike paths any day
