People Who Live With Gators and Crocs Ten-year-old Samantha Young's earliest memories are of her remarkable interactions at the Colorado Gators Reptile Park in Mosca, Colo., where she and her father, Jay Young, help to take care of some 350 alligators. Samantha has learned from her dad how to "wrestle" gators safely to get them out of the water for medical attention, though she leaves the larger ones for her father to handle. <b>Watch the full story on "20/20" on Friday at 10 p.m. ET.</b> Kimberly Launier/ABC News

The temperature of the water remains at 87 degrees Fahrenheit all year round.

People Who Live With Gators and Crocs For Erin Young, dating and later marrying Jay Young meant falling in love with alligators too. "On our third date he made me take the alligator wrestling class … And he said if I wasn't willing to at least try to wrestle alligators, then we might as well quit there," she said. courtesy Animal Planet

People Who Live With Gators and Crocs Colorado Gators Reptile Park was originally a tilapia fish farm. "The reason we got our first alligators was to be garbage disposals for the fish farm," Jay Young said. "Alligators are perfect for getting rid of dead fish… It's over 2,500 pounds per square inch jaw strength there." courtesy Animal Planet

"Johnie's always been a bit dominant over Andrew because she's a crocodile -- she might be younger but she's a crocodile," Lowing said. Courtesy Vicki Lowing

"I do meet nice blokes and then when they do eventually come home and see I've got the crocodiles, they just run. They all run." Courtesy Vicki Lowing
