I just learned about the tag by reading posts on this site, so I stopped into the TNF office on McDowell today and picked up some info. You have to purchase the Golden Eagle Passpost ($65) which is good for 1 year from the purchase date, and then purchase the upgrade. Which I have now learned (courtesy of Bayou) that it must be $30, making it a total of $95. It allows the holder to enter Saguaro, Canyon, Bartlett, Apache, Roosevelt, and heaven forbid we had an overwhelming amount of rain... Horseshoe lake, without paying the $6.00 entrance fee each day.
