The Corn Field is a region of mythological status where once naughty avatars were sent to think about what they had done. "The corn field" is a vast star-lit field of corn and was cut off from communication with the rest of the world (a reference to the classic Twilight Zone episode, "It's a Good Life").Since bad avatars are not sent to The Corn Field anymore and it stayed closed to the public, noone could actually visit it. People only knew about its existence from a single post of an avatar that was once sent there. However, it was opened for October 28-30 this year, yay! It's decorated for Halloween, but I don't mind - my curiosity is sooo satisfied :)

The Corn Field is fun to explore.
But once it gets dark, it can be quite spooky ^^
I won't spoil the fun for you, you have to go and explore yourself, but be aware that almost all the Lindens you'll meet there are zombies. Also, Mia Linden is the most scaaaarrryyyyyy. And if you have a feeling that Lexie Linden is watching and following you, but when you turn around she's not there... SHE IS FOLLOWING YOU! Have fun :)
