It can be crowded and stressful at the airport on the first day of a busy holiday weekend.

But on Friday, at the start of the July 4th weekend, it was a zoo at San Antonio International Airport (SAT).

Not because of the people. But because of the animals.

As part of SAT’s “Summer of Fun,” Zoomagination, an animal advocate program, brought a boa constrictor, an opossum, a parrot, and two sloths to the airport for animal encounters with travelers.

Why two sloths? Sloths sleep 18-20 hours a day, so when Snooze the Sloth needed a nap, Yogi took over.
