Let's get out again before the cold weather starts to set in.

Living where we live, it's safe to say that we love being outside. We have so many gorgeous places to visit right here in our own backyard. I think if we had our choice, we wouldn't work from home, we would work from outside.

As a kid, I was outside constantly. We had 40 acres and I spent much of my time getting lost on the mountain, riding my bike (pretending it was a horse,) and seeing just how dirty I could get before mom called us in for dinner.

It was a childhood that I could easily relive over and over again.

Although I didn't grow up in Colorado, I know there is a familiar love for the outdoors here. I believe many of us are fans of state and national parks. This is why we all need to visit a national park on Wednesday, August 25.

Especially since it will be free.

The National Park Service will be celebrating its 105th birthday by allowing visitors to get in without paying admission. So take advantage of it! Remember, there are some parks that are requiring that you make a reservation, so be sure to plan ahead depending on where you are going.

If I had to guess, those parks that have a reservation policy, are probably booking up fast for this free event.

Can you believe how old the National Park Service is? The organization was created on August 25, 1916, by President Woodrow Wilson. He was the one to sign the National Park Service Act. This act protected 35 national parks and monuments that already existed across the country, as well as those that would be established in the future.

There are now 423 parks across the nation.

Today these parks are located throughout the country in 25 states and the U.S. Virgin Islands. The land encompassing them was either purchased or donated, though much of it had been inhabited by native people for thousands of years before the founding of the United States. These areas are protected and revered as educational resources about the natural world, and as spaces for exploration.

Colorado is home to four national parks and eight national monuments. Our neighbors to the west, Utah, boasts five national parks and seven national monuments. Also within reach are the parks and monuments of New Mexico and Arizona.

If you're the road-trip type, they're all reachable in a day's drive from Colorado.

While the majority of tourists visiting these parks only witness the phenomenal views during the day, there's a sight to be seen under the stars.
