LAS VEGAS — Few places in the scorching Southwest demonstrate the surreal contrast between indoor and outdoor life like Las Vegas, a neon-lit city rich with resorts, casinos, swimming pools, indoor nightclubs and shopping.
Visitors to Las Vegas step out and are hit by blast-furnace air. Most will spend their vacations in a vastly different climate — at casinos where the chilly air conditioning might require a light sweater. Tens of millions of others across California and the Southwest were also scrambling for ways to stay cool and safe from the dangers of extreme heat.
