A prominent columnist for the Dispatch, Joe Blundo used his latest column to take on the Olentangy Trail and its pitfalls, most notably around the OSU area (which has been the most decrepit part of the trail for years).
Apparently, Blundo's been taking the trail to work all summer, and his experiences on it point out the issues at OSU and between Clinton-Como Park and Whetstone Park.
Of course, the latter section is in the bike plan as the recipient of a bike boulevard overhaul, so that problem is not as much a problem. The OSU section is much more a problem, since they've been talking about fixing it for years with no action (other than to tear it up more).
People, not speed.
