In the totally-green-with-envy department, check out this blog of this very lucky fan who got a visit to the Stargate Atlantis set (through an auction)
http://carol-highonscifi.blogspot.com/2007/08/atlantis-set-visit-july-2007.html
Talks about Joe Flanigan, David Nykl, Kavan Smith, Amanda Tapping and more.
It does contain some minor spoilers for the SGA season 4 episode “Quarantine,” so if you’re a spoilerphobe, hmm, might want to avoid, but do check out the photos at the link below. Just set shots, nothing spoilerish.
