In the song "Down In The Alley", Memphis Minnie sings verses about meeting various men who, for example, ask to "pal up with" her and she says yes, take me down in the alley, which is where she can "get his business fixed all right". Towards the end it's about being treated rough and intending to "stop walking, late at night".

song lyrics (http://www.harptab.com/lyrics/ly4422.shtml)
A regulation bowling alley is made of polished wood and measures 41 to 42 in.
(104.1 to 106.7 cm) wide and 60 ft (18.3 m) from the foul line, where the ball is delivered, to the center of the head pin (nearly 63 ft/19.2 m to the end of the alley).
Clearing the alley with two balls is a spare and scores 10 points plus the next roll.
