Yep, I have experienced some of this as well. usually people back up when they see me to be out of the sidewalk. if not, I go behind them and around. this doesn't happen often. No problems with intersections yet. I like this route because it saves me 20 minutes a day! I will probably get tired of it later and go back to the quiet route. thanks for the reminder!
