For the filming of his unappetizingly titled forthcoming show, Feasting on Asphalt, Food Network personality Alton Brown traded in his signature Hawaiian shirt for a black-leather jacket. Looking only slightly more kooky-middle-aged-dad-ish, the 43-year-old Brown rode his motorcycle cross-country in search of decent roadside cuisine. En route, he ate at truck stops, diners, campsites, VFW halls, and private residences, all the while offering up a history of the relationship between food and America’s highways. During his slide- and film clip–illustrated lecture, Brown will discuss his experiences on the road, which include an accidental sacrificing of his body for his art: While shooting in Nevada, he broke his collarbone in an on-camera motorcycle crash. Mmm, asphalt. A rehabbing Brown will also be signing copies of his most recent cookbook, I’m Just Here for More Food: Food x Mixing + Heat = Baking, following the lecture, which begins at 7 p.m. at the Natural History Museum’s Baird Auditorium, 10th St. & Constitution Ave. NW. $28.
