We've been thinking about trying to get something together over NEC weekend - a trip to the aquarium, and setting up a behind-the-scenes tour. I think its $60 for up to 15 people, so if we get a good group together its not too expensive.
I love mystic.... if we set up a group trip I'd TOTALLY be in... though not right away, I just spent all my $$ on a new computer and have $100 until I get another paycheck...
