In order to be the best bowler you can possibly be, you have to know the bowling alley secrets.  These are things you can only learn yourself by trial.  Every bowling alley is different.  Pay attention to how much oil is on the lanes, how far down the oil goes, any problems with the lane itself, and anything else that could affect you at that particular alley.  You must account for everything.  Knowing your alley in and out might just give you the boost you need to raise your average a few points.  And this could make the difference between winning and losing.
