Joy Ryan, 89, has always wanted to see the ocean and visit America's stunning national parks. Thanks to her grandson, Brad, she's doing just that. Brad Ryan and Grandma Joy are working their way through all 61 national parks as part of her bucket list. So far, they've checked off the Grand Canyon, Yellowstone, Yosemite, Redwood, Channel Islands and the Great Sand Dunes, among others. This week, they hit their 31st park, and they have no plans to stop until they make it to all of them.
