We have a lot of exercise trails here too - it's wonderful, really. And people never seem to understand which side they're supposed to be on, although most of the time it doesn't matter. I just don't like being run off the sidewalks of my neighborhood by people on bicycles - especially when I'm trying to walk the dogs (it's a quiet neighborhood; bikes should be in the street in this area, unless you're a little kid IMO)
@Shadami: Are you talking about me by any chance? If so, I prefer the other av, and I'm probably going to change again soon... And if not, ignore this post!
