Though canines love tennis for its bouncy yellow balls, humans appreciate the freedom to bark loudly with each swing and bury their favorite rackets all over the court. Kids become tennis beasts with today's Groupon: for $40, your child can enroll in a summer tennis program at Northgate Country Club. Groupon holders can choose between the Quick Start and beginner programs, both of which consist of two classes a week for four weeks.

Wielding an education in exercise science, pro experience, and 13 years of tennis-camp instruction, Ken Olivier and staff impart a strong foundation of tennis skills in kids while promoting passion for the sport. Set against the lush and polished backdrop of the Northgate Country Club, tennis summer camps are held twice a week and staffed by highly experienced instructors who teach budding tennis fiends the ropes in a supportive environment. The Quick Start program for kids 6–10 years old starts kids off by using smaller courts and foam balls, ensuring serves can foul properly or strike true while little John McEnroes practice and play actual games. The program includes a rundown of all equipment, fundamental skills, and ever-important hand-eye coordination to minimize the risk of bright yellow projectiles blazing holes through courtside water coolers.

In the beginner program, 10–14-year-olds hit full-size courts in their quests for fore- and backhand success. Kids acquire and hone core skills in this camp, dividing their time between drills and scored games. Tennis rackets are included with both camps, preventing kids from having to dig out Grandpa’s steam-powered racket or play with electric flyswatters. A parent (or other approved guest) is welcome to watch, cheer, and lecture at length about his or her halcyon net-eluding backspin-adding days of yore.
