2．Craig grew up on "a gentleman's farm" in Colorado with horses，cows，and chickens.When he was 18，Craig was already running some of the businesses.He planned to earn a business degree in college，but on a fateful trip to Florida，he visited a friend who worked as a grounds-keeper at a zoo. "I just wanted to say hi，but he showed me around，and in the back，I saw lions and tigers in these cages that were so small that you wouldn't want to keep a dog in them，" he says.The animals were surplus（過剩）and would likely be euthanized（使安樂死）.
When a sad Craig returned to Colorado，he called the Denver Zoo about taking the animals，but Denver's zookeepers also had a surplus.Then it occurred to him：Perhaps he could bring the animals to the family farm.He was only 19，but he studied local regulations and formed a nonprofit organization.He next wrote zoos nationwide offering to help if they planned to euthanize animals.
After about five years，he bought a second，larger property before moving to the shelter's current location northeast of Denver.The goal，he says，is to provide the animals with plentiful space and to treat them with dignity and respect. "We have prides of lions that live together，just like they would in the wild，" he says. "They're wandering free and playing and doing what they want.We just give them medical care and food."
Craig opened the shelter to visitors in 2002.Although he was originally unwilling，Craig now sees it as an opportunity to educate more people. "We want the public to know，if they hear about some guy driving around in his Ferrari with a tiger or a lion，they should say，What are you doing？That animal is going to end up dead or in some dirty roadside zoo." The shelter receives 150，000 guests a year.Given his goal of treating the animals with respect-the shelter prohibits feeding and hands-on human contact -visitors observe the animals from a 30-foot-high，1.5-mile-long elevated walkway.
