Happy birthday to our National Parks means that visitors get the presents - free admission to all U.S. National Parks Monday, August 25.

That means no charge to enter Yellowstone, Glacier (see photo) or Big Horn National Battlefield. The other national parks in Montana, such as Big Hole National Battlefield, don't charge entrance fees on any day.

It's the 98th birthday of the National Park Service. President Woodrow Wilson signed the National Park Service Organic Act in 1916.

There will be two more "no charge" days coming up this year.

By the way, I've been to Glacier twice this summer and parking spaces are - shall we say - an endangered species. Traffic on Going to the Sun was just fine, but if you're planning to park, you might want to seriously think about taking the park's buses. They're convenient and you'll be able to spend some quality time at Logan Pass - instead of circling the parking lot.
