Broken glass and tree debris on the road, traffic signals not working, dark streets... all reasons to be very careful out there!
I've been ferrying back-and-forth with my open-top grocery bag panniers to Randall's and Wal-Mart to get supplies during the emergency; did not have to light up my car once. Still sitting in the driveway with a full tank of gas. Haven't driven it in a week.
I'm still, as always, just about the only bicyclist on the roads. You'd think people would figure it out. Bike = huge advantage during a fuel crisis. Do ya think?
