Took 2 years, but the hours on the Monon Trail (the trail in the original link) have been extended for the winter as a test. Cycling commuters will be able to use that trail, but it also means the trail is open to everyone after dark, which is most likely to spur some additional crime opportunities (most of the crime on that trail happens after dark when folks are walking home from bars near the trail). Hopefully any increase in trail crime doesn't harm the positive impact of the trail being open for commuters.
