With the summer travel season officially here, millions of folks will be heading out into the National Park System in the coming months. If you're one of them, just remember to be mindful of your safety, and that of your family and friends.

Crews were making progress Sunday at clearing away a rock slide that had isolated the northeastern corner of Yellowstone National Park, but no estimate was given as to when the road between Mammoth Hot Springs and Tower Junction would be reopened.

With spring still on its way to the Rockies and High Sierra, and summer well under way in some parts of the country, this seems a perfect time to honor all 2010 Appalachian Trail thru-hikers, consider ways to support national parks, and look at ways to enjoy the parks.

Mention "National Recreation Trail" and no one would be surprised if you immediately thought about taking a hike. But soon that tag will be attached to a watery route in Lake Michigan.
