Here are all the results with descriptions
On Mars
You're up for a risk and not afraid of going out on your own. Plus, a little dirt never hurt anyone. Living on Mars would feed your adventurous side and you would easily handle the surprises.
In a Tent
You like the outdoors, but you're happier shielded from the elements inside a cozy tent (or a screened-in porch). You're laid back enough to sleep on the ground, but it wouldn't hurt if you had a comfortable sleeping bag.
Up a Tree
You like your alone time and prefer things to be somewhat organized and in order. You're more comfortable when you are in control and know what's going on. Up a tree, you can enjoy nature and your comfortable hammock, and keep an eye out for anyone who is coming or going.
In a Cave
You don't really sweat the small stuff. Life's too short to spend time worrying about things that aren't important, right? You're not too picky, but you do have one or two things you like a certain way (your coffee? your kitchen sink?). In your cave, you would be able to deal with the darkness and the dampness, and would enjoy having your little underground kingdom to yourself.
On a Houseboat
You're pretty steady, not much gets to you as you prefer to understand a situation before you react. You keep your life fairly in order, clean house, planned schedule, but every once in a while you surprise people with your ability to take a risk. On a houseboat, you would enjoy the serenity of the moving water and your frequent visitors.
In an Amusement Park
You haven't quite grown up, but for the most part, that's a good thing. You love to be around people and really could go without any time alone and be okay. Living in an amusement park would satisfy your need for constant entertainment and ensure that you always had company.
