Virtual touring comes at the speed of the Internet, allowing one to sample popular places and moments. For example, in Yellowstone National Park (www.nps.gov/archive/yell/oldfaithfulcam.htm) one webcam sends a new photo every 30 seconds of Old Faithful's periodic eruptions.At this time of year, the local buffalo appreciate the warm ground as a light snow covers all but Old Failful's cone.
