I didn't know that there were MUPs that had a point. I haven't seen one yet. Most go from nowhere to nowhere with not much in between. Most end abruptly in a barricade, like the one you're talking about; or they dump you out onto some road in the middle of a maze of a residential section and you have to have a detailed map to get from where the MUP left you to where you might actually want to go; or they drop you on an incredibly busy highway, which you have to cross in order to get to the rest of the MUP, or quieter streets.

I strongly dislike MUPs at the best of times because of the very fact that they are MUPs (multiple use paths) and therefore the users are moving at a wide range of speeds from very slow walkers to roller bladers to cyclists, with dogs and children running to and fro into your spokes, under your bicycle, and around your pedals. They are usually built with numerous blind spots so that you can't see the old ladies standing in the middle of the path pointing at the trees, or the rollerblader blading backward with headphones, on around the corner. And you plow right into them at the last second. IMO MUPs are extremely dangerous places. I'd rather take my chances with the road.

However, IF a city built a MUP (or prefereably a Bicycle Path that banned all other uses) that went straight from one end of the city to the other, bypassing traffic lights and all that sort of thing, and through the downtown so that downtown workers could use it ... I might actually use them. They'd be a quick way to get through a city and back onto the country roads where I like to ride.
