Visiting America’s national parks will forever change you. The remarkable beauty that these vast areas have to offer is almost impossible to truly describe — which is why people are often tempted to take a piece of the park home with them in the form of a plant, rock, or something more precious. But it should go without saying you should never, ever vandalize or steal from a national park.
Some people, it seems, didn’t get that memo. And it’s become such an issue that rangers at Saguaro National Park in Arizona have been forced to put microchips in some of the park’s famed Saguaros, a variety of cactus that is capable of growing more than 40 feet tall and can live upwards of 200 years.
