Google just made it easier to visit some of the US' biggest landmarks without hopping on an airplane. It's teaming up with the National Park Service to offer 360-degree Street View imagery for 40 national parks and historic sites, ranging from Alcatraz's legendary prison to the ancient cliff dwellings of Montezuma Castle. The collection also touts photos of artifacts from those locations. Want to see furniture from Abraham Lincoln's house? You can. No, this won't recreate the grandeur you'd get from being there yourself, but it beats having to rely on tourists' photos to get a feel for what you're missing.
