Marina Billiards located near Marina Del Rey just West of Los Angeles was a small pool room with a lot of action in the late 1960s and early 1970s.
One of the housemen was Lou "Machine Gun" Butera, who won the World Poker Billiards Championship in 1973.
When Lou would teach a pool lesson the first question he would ask is, "How many hours a day do you practice?".
This was because the answer would tell him what kind of lesson he would teach.
