Traveling into Yellowstone National Park this weekend from West Yellowstone? Watch out for wranglers herding hundreds of bison back into the park.

There is one place in the National Park System where the fireflies are almost like a well-conducted orchestra in that they all blink in unison. And if you head to Great Smoky Mountains National Park now, you just might see that performance.

"Death Valley Scotty" was a raconteur to most, a rapscallion to others, and a legend in the landscape now known as Death Valley National Park. With that background, it's fitting that the last known portrait of Scotty is back in the park.
