Fuel Economy

Here is a log of my fuel economy, in mostly metro driving.  My normal routes are somewhat worse than the EPA city cycle for fuel economy -- the EPA routes don't include sitting with the car running in fast food lines, or to pick up the kids from school.  Mileage taken per the car's fuel computer.
