Sometimes when I'm glazing over at work and it's all too intense, I'll pop up a webcam window and let my mind decompress with a mini-break looking at Old Faithful or Mount St Helens venting spleen. I love seeing the ships rising and lowering in the locks at the Panama canal, and every once in a while you'll see deer in Awanhee meadow at Yosemite. It's also interesting to see how the weather is differing in those other parts of the country.
My favorite webcams:
Mount St Helens
Yellowstone's Old Faithful cam
If you google "webcam dashboard," you'll be amazed at the webcams you'll come up with, most likely including some of your favorite getaway spots. Have a nice trip!
