Want to know what Yosemite National Park looks like right now? I found this interesting app that takes you on a map tour of our National Parks via live webcams.
I found some of the webcams not working or displaying an old image, but the ones that do work give a great picture of that area about the time you load the app. I found if you reload the app a few minutes later, those webcams that are working will update their video feed. Pretty cool.
