We walk our dogs on a local multi-use trial for hikers/bikes/horses and the bikers come out of nowhere and make little effort to slow, mostly if we are really alert we have just enough time to pull our dogs aside and make way for the spandex bunch who have the attitude that they have the right of way, they don't! Before Paul tells me how biased I am, I've bought five bikes from local shops over the last decade but have mostly given up riding due to the azzwipes that fancy it in my city and they dangers of riding on the road. As far as I know, they rules for biking on multi-use trails suggest that they must ride under control and yield to horses and walkers.
