I see in the papers that pool is now played by college boys and suburban families in wholesome, well-lighted establishments where you couldn't get a bet down if you were shooting with broken fingers. Which makes me sad. Pool halls were perfectly sleazy in my day. The guys were often downright unpleasant, and a lot of them were such creeps you wouldn't introduce them to G. Gordon Liddy, let alone Mom.

P.S.: I had talked with G. Gordon once...a very interesting guy.
