Selmer, Tenn., is a small town near the Mississippi border where former-major-highways U.S. 45 and  64 (a once-popular east-coast-to-west-coast route known as Lee Highway) intersect. This brought more than traffic to Selmer — in the 1940s and ’50s, it helped meld the meeting of country, rock, swing and bluegrass into  what’s known as rockabilly music.  In fact, Selmer folks probably would much rather you think “rockabilly” when you think of their town instead of thinking, for example, “Buford Pusser.” And who wouldn’t want that? Downtown Selmer is a great spot for wandering around and poking around and discovering treasures such as the Rockabilly Highway Murals by Tennessee artist Brian Tull. Tull’s second mural was dedicated this past Saturday during the annual Rockabilly Highway Festival, held downtown and featuring music, art and Selmer’s version of the deep-fried doughburger called a slugburger. Go ahead — you know you want to try it.
