Heat upends Texans’ daily lives: ‘Anything after 11 o’clock, I’m down’

For street ice-cream sellers, seniors lacking air-conditioning and even animals in the zoo, relief from extreme temperatures is hard to come by

Just after 8am, when temperatures are already reaching 80F, Mark Jalufka arrives at Sam's Club to pick up 20 cases of bottled water.

Jalufka is the general manager of the Lions Club Tube Rental in San Marcos, Texas. Every day during the summer, he rents inflatable inner tubes to hundreds of Texans looking to cool off in the spring-fed San Marcos River. He and his staff work outside all day, and that means he needs lots of water.
