The TechEd 2006 site now has details of the attendee party on June 15th. The main event will be a private concert by the band Train.
From the special events page:
"Throughout the night you can enjoy traditional ballpark food and beverages as you tour the historic park learning facts and trivia from Fenway Tour Guides. Don’t forget to bring your camera! Top tier Red Sox alumni will be on hand to sign autographs, you can take a close-up look at the World Series Trophy and other memorabilia collected through the ages. Batting cages and speed pitch cages will be open if you want to test your skills (all gear provided), you can take a walk up to the top of the famous “Green Monster” or simply sit back and enjoy the beautiful view from one of the upper decks, bars or club lounges - all seating areas will be open for you to enjoy."
See you there!
