If someone you're really not on good terms with randomly invites you on a trip to Yellowstone National Park, you might want to say "Thanks" but "No Thanks".
Yellowstone National Park has plans to test driverless shuttles on two routes this summer, and what they learn could change how we get around the park forever.
Famous national landmarks aren't to be messed with, and if you get too close to them, in some cases you can get a ticket. I'll tell you what one man did at a place I visited this summer, so you don't make the same bonehead mistake.
We have some great hot springs in Texas that have become swimming holes, but you wouldn't even want to dip a toe into this one. Do you know where it is?
