With its catching meshes and hard-hitting action, lacrosse is similar to America's national pastime, extreme lepidoptery, though it involves fewer swarms of carnivorous butterflies. Discover the delights of this simpler sport with today's Groupon: for $182, you get a four-day boys lacrosse camp at GameBreaker Lacrosse Camps in Bloomfield (a $365 value). The camp takes place from August 8 to August 11. Campers are required to bring their own stick, pads, gloves, helmet, and cleats.

Since GameBreaker's inception, nearly 40,000 budding sports stars and novice stick-handlers have passed through its lacrosse camps at nearly 120 locations throughout the country—bolstering their field skills with expert instruction from college coaches, players, and high-school coaches. GameBreaker divides its four-day camp into three divisions based on age, and each day focuses on skill exercises such as shooting, dodging, stick control, and scooping ground balls away from mischievous Tremors worms. The teaching staff gives each camper one-on-one advice about proper positioning, man-up and man-down situations, and the exfoliating benefits of regular Gatorade baths, which students can then apply during full-squad scrimmages. GameBreaker Lacrosse camps also tailor specific lessons for goalies. Each camper returns home laden with an authentic reversible jersey, water bottle, and lanyard.
