George Dailey, ESRI Education Program manager, has published Part 2 and Part 3 of his continuing series on exploring America's National Parks using ArcGIS Explorer. You can check them out on the GIS Education Community blog.  

In conjunction with the new PBS National Parks series, George Dailey's My National Parks and ArcGIS Explorer blog series begins today. Yesterday we posted about how to add Yellowstone National Park's Old Faithful Web cam to your Explorer map, and we'll be following along with additional National Park topics.
