So, it's pricey, but where else can you jog or walk on a shock-absorbing one-mile outdoor track set against 30 acres of lush pecan, red oak and cedar trees? Where else are the ducks, geese and squirrels so relaxed in their natural habitat they actually risk asking you for spare change? Face it, there is no place like the Cooper Fitness Center, which is why there is still a waiting list to get in. But with its two heated 25-yard, six-lane pools, its 4,200-square-foot weight training area, its sizable cardiovascular equipment area, its indoor basketball and outdoor tennis courts, its multiple saunas, steam rooms and whirlpools, its close association with the Cooper guest lodge, spa and clinic--hell, it just might be worth the wait.
