this happened to me a couple of days ago. I was riding on the bike/walking path in a very low traffic area, the bike path follows along side the country road and maybe at times gets within 8-10 feet or so of the county road. I had not seen another person walking or biking on the path except my wife who was a riding a couple hundred feet behind me. In fact I don't think I have ever encountered anyone else on this path ever. A freaking US mail carrier who was probably pushing 70 stopped and got out of his mail jeep and started waving a red bucket at me, to get my attention I guess, and yelled at me to stay on the very right side of the path. Kind of caught me by surprise. I said "excuse me" and he said he thought that I was taking up too much of the path and needed to stay to the far right at all times..no wonder we have such crappy mail service....
