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 it 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 Wyoming, I know there is a familiar love for the outdoors here. And I believe many of us are fans of state and national parks. Which 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 their 105th birthday by allowing visitors to get in without paying admission. So take advantage of it! But 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.

And 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.

Just The Facts: Size Doesn't Matter For Wyoming's War Memorial Stadium

Did you know it would take the populations of Gillette (32,857), Laramie (32,381), Rock Springs (23,319), Sheridan (17,844) and Wright (1,200) to create a sellout inside Michigan's famed 107,601-seat Big House, the largest college football stadium in the nation?

For those of you not familiar with the Cowboy State, those are Wyoming's third through sixth most inhabited cities, along with the small mining town in Campbell County.

Wyoming Restaurants Featured on Diners, Drive-Ins and Dives

It's hard not to take this a little personally. Guy Fieri of the Food Network's Diners, Drive-Ins, and Dives has visited the Cowboy State a few times. Yet each time he stays close to Jackson. The show takes us on a culinary voyage across the U.S, but he's never stopped in Cheyenne, Casper, or even Chugwater.
