Who couldn't use a free day at a National Park this summer with the economy the way it is? I was so excited to hear about this because Brandy and I are lucky enough to live admist quite a few National Parks.
Each park has their own free days so you need to search for individual parks. Here is the link for Zion National Park, there will be a search engine that you can type in other parks to find out their free days. We will be in Yellowstone during their free day for a family reunion, it will be super busy, but at least it will be free!!
