Oklahoma City

Oklahoma City residents used to 70-mile commutes are turning to carpooling as gas hovers at $4 a gallon. But with the largest land area of any U.S. city, providing public transit remains a major challenge.

At one time, Oklahoma City is doing two things many cities have only hoped to: the city's getting rid of one of its aging inner-city highways and replacing it with a park.

Officials in Oklahoma is hoping to woo the Seattle Supersonics to relocate in Oklahoma City by offering tax incentives. One politician is hoping to advance plans for a light rail transit system by planting the idea with team officials.
