also, there was apparently a murder on the main drag 2 blocks from our house this morning, so its traffic was diverted one block in, toward our house. So when my 8 yr old and I rode against that flow to his school, on the sidewalk like we usually do, I rode back with the flow (but faster than it) on the sidewalk again rather than bombing down the center of the usually vacant narrow street. This time I didn't have to worry about cars jumping out of driveways or sidestreets because they were all blocked in by the diverted traffic.
