The September 28 celebration of the 10th anniversary of Chicago's Critical Mass ride may also be the marking of its end, as reported in the Sun Times. The large draw of participants dedicated to showing the benefits of cycling is apparently causing more problems than displaying productive transit solutions; apparently no one likes a group of loud, drunk folks on bikes (but if you've seen a Critical Mass ride, you know that hardly describes the majority of riders). Before you start crying in despair, note that no formal plans have been made to shut down the ride, which is scheduled for the last Friday of every month at 5:30 p.m. in Daley Plaza.
