A portal to another world opens in front of you. You don’t know how long it will stay open or if you’ll be able to get back after you go through. What do you do?And which world would you choose ? A reminder , you might not be able to get back again !

Years ago I would have picked the Star Trek world, but it's too sanitized for my taste these days. Maybe I'd open it up and wait for a himehorn to wander into my world.
