Cal Bannon, 85, plays tennis for fun and exercise with the "morning group" at the Bob Booth Tennis Courts across from the north side of Lincoln Park.

"He and the other 80-something players in the group are remarkable," says Flora Belle Key, a teammate still in her 70s. "They have good shots, and they can still scramble around the court very well. They are serious competitors."

"And we're all friends. After all, tennis is a 'love' game," she says with a grin. "We have a lot of fun. We even have parties - sometimes right on the court. We play year-round, even on wet courts, as long as there's no standing water."

Bannon and Key are part of the group's loose assortment of over 16 men and women players of various ages and ethnic backgrounds. Some have been playing there for more than 20 years, while others just show up for the first time to play in the pick - up tennis games, which are mostly doubles.

"We need tennis players," says Cal. "Some mornings we are down to three of four players because of vacations, relocations, or other commitments. We welcome drop-ins. No reservations needed."

The tennis courts, located near 8600 Fauntleroy Way, feature six well maintained and lighted courts with adjacent parking, water fountain and portable toilets - all free to the public.

Key invites any one interested in a fun morning of tennis to join her group at 9 a.m. every Tuesday, Thursday, Saturday, and Sunday.
