It makes a difference if you know the road you are traveling. Last Friday we were traveling to a campground about an hour from the house. There is about a 25 mile long section of 2 lane we travel. And really only one location along there that is large enough to pull over and let others by. It's not an official "turnout". If you look for one of those here in PA you will never find one. Just a spot where a local small business has gravel and parks some truck trailers. It sits just around a curve in the road and if you don't know it's there you drive by saying "Oh, I could have pulled off there" as you go by.
