AMF Bowling Centers Inc. (A Bowlmor AMF Company), Milford

"You're up." At more than 200 AMF Bowling locations across the U.S., that message is passed between friends as they heft a ball, step to the line, and take aim. Now synonymous with bowling, AMF was founded in 1901 as American Machine and Foundry. It wasn't until 1946 that the company made a splash in bowling, when it introduced the automated pin spotter to the public. Today, AMF's nationwide network of bowling centers is a source of year-round entertainment for people of all ages. Outfitted with a classic bowling alley design, the centers also feature the latest technologies, from high-tech scoring systems to the ability to share experiences on social media. Bowlers can also refuel on a menu of American foods when they get hungry or the little heart-shaped meter above their heads begins blinking.
