I sent a text to my wife and she called me after work just marveling about it. Her first reaction was "what the fuck?"
We can so relate. We were both at work as well when we found out we won, and couldn't really show any emotion about it w/o having someone ask what's up?
"Oh, we just won a contest for free passes to a swinger convention." Don't wanna give our vanilla coworkers jaw-drop-itis.

Of course, a condition for going would be a visit to see the manatees.
Strangely enough, us too. On the way up and/or back we're stopping in at Manatee Springs State Park. It's not the favorable time of the season for potential manatee sightings, but it's still a very cool place. Unfortunately, it's not close to SwingFest, so quick daytrips are out of the question.
(Wow...who'd have thought a manatee discussion would break out on the SwingerCast forum?)
