The eDodo is the electronic version of the U.S. Air Force Academy's underground cadet humor magazine -- so irreverent and cynical that the 'powers that be' firewalled the site at USAFA. Their Rumor Mill message board is a good place where Academy grads, former cadets and those associated with the AF in one form or another (enlisted, former enlisted (like me)) can catch up on some of the latest stuff going on in the AF or complain that 'what happened to the Oooooold Air Force, and you know the Oooooold Air Force was the BEST Air Force...'
etc. etc. and so forth.
The other two sites I visit regularly are ones that cater to my other passion: collecting die-cast model aircraft.
