I can't get to any link for the United States Forest Service websites anymore.
All the various ranger stations, forest service campgrounds, etc., used to be at
fs.usda.gov website addresses, but now all the web browsers just say:
fs.usda.gov’s server IP address could not be found.
Somebody messed up a DNS record somewhere and thousands of web pages vanished?
For example, go here and try clicking on any of the Geo-enabled PDFs in the "Topographic Maps" section.
