Any tennis player worth his Tretorns knows that there is more to the game than ground strokes and serves. Sure, drills on these essentials will consume an entire day's program at Tennis & Life Camp, held on the campus of Gustavus Adolphus College in St. Peter, but developing strategy, sportsmanship, nutrition and concentration are given equal weight. An added bonus: You get to relive your college days (or look forward to them) since you bunk in dorm rooms for three nights. Camps for families, adults and juniors run June through July. 800 W.
