This is one of those cases where you worry about your rights being trampled upon: there are lots of horror stories about overzealous police confiscating cameras and such when you're taking pictures from public property. I never experienced it, and still haven't, so I can't address the truth of it. Still, when you're trudging up the edge of a very busy highway with no sidewalk and in one case not even a shoulder on the side you're on, you worry about such things as "do I stick out like a sore thumb" and also "will I get hit". Obviously, I did not get hit, and I had no police troubles.
Men's dress shoes are probably not the best for trudging along the edge of a highway in an inch or 2 of snow, but I'm too vain for the athletic shoe look. ;-)
(Of course, I went outside in said shoes earlier and promptly fell on my ass because there was a small bit of ice on my front steps, so what does that tell you?)
