Paintball simulates the experience of live combat in a safe manner, much like professional wrestling matches and barroom brawls among mimes. Get real adrenaline flowing with today's Groupon: for $19, you get a paintball-outing package, which includes a three-hour admission, 100 paintballs, face mask and gun rental, air, and air refills at Tag Paintball in Hollister (a $39.99 value). This Groupon is valid for a full morning session from 9 a.m. to 12 p.m. on Saturday or Sunday.

Tag Paintball's sprawling outdoor campus hosts pretend warfare on more than 12 realistic courses. Players juke behind an abandoned pickup and hide in hollowed-out shipping containers on the Close Quarters Battlefield or duck behind mounds and ask their camels to stay quiet on the Desert Dunes course. Between games, combatants can rest up and reload depleted canisters in the 4,000-square-foot covered staging area. Participants can purchase extra eco-friendly munitions ($6 for 100; $21 for 500; $37 for 1,000; $63 for 2,000), which won't stain any clothing or powdered wigs.
