The people living in drains below Las Vegas | The Sun |Features: "Despite the risks from disease, highly venomous spiders and flooding washing them away, many of the tunnel people have put together elaborate camps with furniture, ornaments and shelves filled with belongings.
Steven and girlfriend Kathryn's base - under Caesar's Palace casino - is one of the most elaborate. They even have a kettle and a makeshift shower fabricated out of an office drinking water dispenser."
I guess it's a trade off. You have to put up with deadly spiders and the risk of floods. But on the other hand, you have no mortgage and no HOA.
