In Denver, the “Mile High” city, platform tennis had found a new frontier and was slowly but steadily increasing in popularity. In addition to courts at two clubs and several private courts, more were being planned at a third. All of these facilities were within fifteen minutes of each other, making future tournaments more feasible. Sally Burbank of Englewood, Colorado, had given much of her time to teaching and promoting platform tennis, free of charge.
