Black Friday just got a lot greener. Instead of trying to elbow their way through a crowded mall looking for a bargain, many Americans are deciding to #optoutside instead.

Retailer Recreational Equipment Inc., commonly known as REI, announced in October that it would keep its stores closed on the day after Thanksgiving to let its employees and customers spend time outdoors. Several state parks have decided to #optoutside and offer free admission this Friday. Here’s a look at some of your options at parks across the country that are pairing sales and sunsets.

All 42 of Colorado’s state parks will be free on what is being dubbed Fresh Air Friday. “On the day after Thanksgiving, we now have the choice of running around indoors or enjoying our spectacular Colorado outdoors for free,” said Luis Benitez, director of the Colorado Outdoor Recreation Industry Office.
