I live next to the Minuteman Trial, which is a MUP built in place of an old commuter rail. This strip of asphalt starts in Somerville and ends in Concord and is usually full of bikers, pedestrians, dog walkers, etc. especially on weekends.
And that's where the problem is. Minuteman is used by "Sunday bikers" and families with kids and dogs. This means, it is difficult to predict its users' behavior. Kids like to run all over the place, dogs feel free to run across the path and many parents and dog owners simply don't pay attention to this or just don't care. This makes places like Minuteman Trial a path for only a very relaxed riding. My Schwinn works well here. I am afraid to ride too fast on Minuteman on weekends as I never know what those that I pass would do. Ironically, when I am on my Poprad, I feel safer riding on streets between cars than on the fully-loaded Minuteman Trial. Cars seem simply more predictable (I keep telling Elka this).
However, to my surprise, there is a large number of lycra-clad bikers on fast road bikes who treat this path like a racing strip. When me and Dr. J. take a stroll on Minuteman we are passed by legions of those bikers yelling only "On your left!", like they would want us to just dissapear or at least leave them more space on their racing strip.
Another, similar path is the Canal Service Road on both sides of the Cape Cod Canal (especially its northen bank). Same rules apply here. This MUP becomes really crowdied on summer weekends and riding too fast there may not be the smartest idea.
