Since the popularization of the laser handshake, the laser hug, and laser diplomacy, laser warfare has ended, and glow-in-the-dark space terrain has been recognized as an independent state. Eradicate holdout anti-nationalists with today's Groupon: for $10, you get three hours of unlimited laser tag (a $20 value) at LaZerCity in El Dorado Hills. This Groupon is only good for play Thursday through Saturday. Play times are from 6 p.m. to 9 p.m. on Thursday; 9 p.m. to midnight on Friday; and 6 p.m. to 9 p.m. or 9 p.m. to midnight on Saturday.

LaZerCity gives laser lovers an exciting venue to practice blaster tag tricks during its Unlimited LaZertag (valued at $20 per session), a three-hour excursion through a neon-lit darkness filled with fog. LaZerCity provides the lightest available laser-tag equipment, allowing both adults and future adults to play with ease while dodging each other’s faux bullets in faux slow motion. Beyond the city of lasers’ brilliant gates, a network of dark passageways houses distant planets, neutral-for-now transformers, and skirmishing space cruisers illustrated in bright greens, oranges, and pinks. As players sneak through the corridors flinging sparks of light from their weapons, a bluish, shimmering floor and highlighted pillars mark the path to lasery illumination.

Laser tag is ideal for families, coworkers, and blind dates, since in its entire history it has not produced one casualty, and, unlike rotten-breadfruit tag, it never leaves participants with a bad taste in or near their mouths.
