OTOH, Portland has one MUP that is totally horrible, with poor pavement, tight turns around obstacles, roots tenting the path surface, signs everywhere dictating that cyclists "must stay on the path - respect the property rights of others", and a 10 mph speed limit for cyclists. Those last two items aren't necessarily bad, but the heavy-handed way that path users are bombarded with the message leaves something to be desired.
