Insider Saver Laura Thornquist has deals on park entry and easy ways to give back to the community.

If you are looking for something to do this weekend, why not visit one of the nearly 400 National Parks. In honor of Martin Luther King Jr. weekend, entrance to one of these parks is completely free. Locally, some of the national parks include the Lyndon B. Johnson National Historical Park, Palo Alto Battlefield National Historical Park or Big Bend National Park.

You can get in for FREE through Monday.

And here's a way to make an easy donation to the USO. CVS is donating $3 to the USO every page visit they get through January 31. CVS hopes to reach its maximum donation of $50,000.

An easy way to make a difference.
