However, the hottest bodies — and I don’t mean that in the People magazine sense — were those sweaty souls working the trucks today. I decided to find out how, if at all, some of the trucks were dealing with the heat. The first thing I learned: The trucks that park on the shady side of Farragut Square have won half the battle.

Jose Gonzalez set me straight: It’s an air conditioner: an AC unit, I should note, that was losing its battle with the summer heat, even though Amorini Panini was parked on the shady side of the square. Gonzalez said the temperature in his truck was still in the 90s. I placed my hand over the AC vents and felt nothing but semi-warm air streaming out.

Just ask Kelly Willis at the Big Cheese truck. All she and her co-workers had to combat the heat were a pair of fans. They provided little comfort. Despite having her hair pinned back and despite wearing shorts and a T-shirt, Willis was glistening like a cold can of Pepsi in the August sun.

Onboard AC may not solve his problems. The employees over at the Surfside truck have one of those small, overhead AC units in their vehicle, and yet Ilder Rivera and crew will still sweating like Irish cops walking the beat on a hot summer day in Chicago. It didn’t help, of course, that Surfside’s cab door and ordering window were wide open to the sweltering heat.

That might sound hot by frigid brick-and-mortar office standards, but the guys appeared absolutely relaxed in their mobile hothouse. Then again, maybe that’s because at least one of them had an unfair advantage: Palisi said he’s from New Orleans. He’s used to all this heat.
