Holiday travelers who plan on driving to their destination can expect low prices at the pump this Thanksgiving. A gallon of gas was at a four-year high of $2.90 in October, but has plummeted since then because of growing oil supplies. AAA says the national average Wednesday was $2.68 a gallon. Prices could drop even further by the holiday. More than 54-million Americans are expected to travel at least 50 miles for Thanksgiving.
