In my misspent youth, I burned more than my share of hours in bars shooting pool for money. I shot all over suburban Chicago and in a little Greek greasy-spoon under the "el" tracks by Loyola that isn't there any more. On particle-board cheapo tables with a topography like the Grand Tetons in morgue-lit bowling-alley-adjacent pool halls, and on the good slate and manicured felt at Southport Lanes.
