Yeah - I have to agree with most of the people here. Unless you go out in bad weather when no one else is on them, multi use paths are asking for trouble if you want to go at more than a walking pace. Walkers and especially baby strollers two and three abreast often blissfully ignore the others on the trail and then totally freak if you even pass them at a creep. We have a fair amount of trail ettiquete education and sometimes even striped lanes, but it makes little difference. We even have one trail and a part of another that has completely separated walking and wheeled trails and walkers still insist on taking up the bike path.
And of course to add to it you have to watch out for other bicyclists who are being bone headed as well. The only time I've ever gone down and gotten road rash was on a trail - it was actually caused by another bicycle - the trail was coming to a T-type intersection - dumb dude decided to cut off the corner and came around on the wrong side of the trail. Hubby had to slam on his brakes to not hit him and I close behind touched his wheel and went over over. I also heard about a bad bike-bike accident out here last year. Some poor woman broke both wrists when she was hit head on by an earphone wearing cyclist riding on the wrong side of the trail.
