I have been in many places, but I've never been in Cahoots. Apparently, you can't go alone. You have to be in Cahoots with someone.
I've also never been in Cognito. I hear no one recognizes you there.
I have, however, been in Sane. They don't have an airport; you have to be driven there. I have made several trips there, thanks to my friends, family, and work.
I would like to go to Conclusions, but you have to jump, and I'm not too keen on physical activity anymore.
