I love having enough land/prim to have several skyboxes in SL. One I have in Caledon Mayfair is open to the public - basically it's open to anyone who discovers it, or to a few people I know who need a large building platform.
Another I have allows even more freedom ;)
Sometimes I'll go to one of my skyboxes and stay the entire time I'm inworld.
Now you may be wondering..."If I IM Zoe, is she wearing any clothes?"
