Of course they are different. It's the only place I have seen with STOP signs on the exit of the roundabout.
I’ve never driven in New England. Of course, there’s plenty of stop and other traffic signs around where I live (western Wisconsin), but I don’t feel unduly put out. I’ll have to take drive a through New England some time to see what bugs Steyn so unduly. I take it from your comment you are unduly bugged by NE traffic signs as well.
