As this AP video explains, Mayor Bloomberg is trying to ease the build-up of lines at gas stations throughout the Bronx and the rest of New York City. The system is pretty simple — if your license plate ends with an even number you can fill up on even numbered day and the same for cars that have license plates that end in odd numbers. For example, today is Nov. 9, so cars with odd-numbered ending plates can fill up today. Evens will go tomorrow. A couple of Twitter feeds have sprung up to help people find gas stations that actually have gas, including @BronxGasFinder.
