As usual another discussion hijacked. It's not helpful to anyone and I find it boring to say the least.
As for the original subject, I would always go for the rural route. It's not a cakewalk, but fewer stops is always better especially for us older folks. I'm almost 52 and have been doing this job for 27 years. To say that if your body is used to it then it doesn't matter is laughable. 70 pounds is much heavier for me at 52 than it was when I was 25. What I find interesting is that most of the injuries here are happening to the younger people. Perhaps it's because they seem to think they are invincible. I know for a fact I am not.
Live and learn.....
