One I'll never forget.
South Gate, Calif on the grass courts, at the park, played tennis with Pancho Gonzales for about 20 minutes.
Had a hard time trying to return his serve at about 110 mph, today they get up to about 145 tops and the hard hitters average about 125-135, mostly because of the changes in the rackets.
In his day he was at the top, a gentleman with a temper on the court.
