Also my thought..but you know, this is why I don't ride MUPs except bits here and there for transportation. Like, on my standard "scenic route" commute, there are sections of two different MUPs. I never, ever expect to be able to go at full speed on a MUP; a cyclist at full boil on a MUP is the fastest thing in a very mixed-traffic environment. They can call it a "bike path" all they wat, but look at reality and admit that it's really not meant for the kind of fast, impediment-free riding that the average roadie is looking for.
