Another Minnesotan here. As with any trail system, there are always going to be certain trails that are busier than others and some that are busier at certain times. I absolutely love most of the trails in the Twin Cities, but I know that if I'm riding the River Road trails or the new Browns Creek Trail or the Greenway Trail, it's going to be busier than most others, and I'll have adapt to the traffic. I don't know if it's reasonable to expect MUPs to be user-free while you're out on a bike ride - maybe not the best places to be trying for a personal best. But as the photos show in previous posts, the trails here are beautiful! If I want to ride in solitude, the best routes for me are the gravel roads I ride out in the country.
