Gas prices are cheaper this holiday weekend, which is one reason why more people will travel. Last Memorial Day, the national average for a gallon of regular was $3.59. This spring, thanks to lower crude oil prices, gasoline prices haven’t seen typical seasonal spikes. In North Carolina, the average price of gasoline is $2.89.

Memorial Day is a U.S. holiday that's supposed to be about mourning the nation's fallen service members, but it's come to anchor the unofficial start of summer and a long weekend of travel and discounts on anything from mattresses to lawn mowers.
