Nearly 30 silver Airstreamⓘ trailers gathered along the Pamlico River in Washington, North Carolina, this weekend for the Carolinas Airstream Club's Urban Rally. According to AAA, the national average for a gallon of regular unleaded is about $4.30, North Carolina's average is about $3.96, and many eastern stations posted $3.99. Owners report their trucks average about 10 mpg on flat highways and closer to 8 mpg in mountains, and are adapting with fuel-discount cards, route planning for cheaper fuel, and packing meals. Organizers expect the rally to provide an economic boost to downtown businesses and restaurants.
