I use a shared use path and I'm coming more and more to the conclusion that cyclists are a nuisance on them, I tolerate it because occasionally I like to cycle on it. The speed differential between bikes and peds means as a ped you are always moving to one side for bikes. As a dog walker then you are constantly on the lookout for bikes in order to get the dog under control before they arrive. In return, I guess 50% acknowledge your effort and 25% don't and are going far too fast on the path anyway, treating you more or less as a mobile chicane. I'm rapidly starting to become a bit militant for the one's who aren't slowing down and step deliberately in their way, woe betide anyone that hits me. So I'm for making cyclists keep to the speed limit, no matter whether it's empty or not, tough sh!t.
