Here are prob the worst courts Ive played on...
1) Where we used to play our matches on grass they marked the service box at one end about 3ft too much. Luckily it was at the beginning of the season so they had time to change it!
2) At a junior coaching session we used to train indoors at a local school on varnished gym floor. The Balls stayed low and fast. Def improved yor reactions tho.
