Kajero, I pretty much avoid the multi-use trails around the Twin Cities during the summer months, especially the ones around the lakes, for just this reason. There are far too many self-centered idiots on those trails and it's just not worth it. The roads - especially wide-shouldered or with bike lanes - are safer for a cyclist. I do wander over to those trails in early spring (but not this year!) and late fall as then I can enjoy the scenery without being worried about the hordes of clueless wonders.
