Last summer our family drove through Bear Country USA in South Dakota. Bears, elk and other animals came up close to our car, but we still felt rather safe. I'm not so sure I'd ever want to drive up close to a den of lions. Especially ones that know how to open car doors.

When I first saw this video, I jumped and my heart may have skipped a beat. Watch one of the lions literally open up the passenger door. (Probably looking for a tourist snack). Yikes!
