In a perfect world I would live in a big beautiful beachfront house. One side of the house would walk out into the sand, and on the other side of the house there would be a nice big fenced in grassy back yard for the dogs to play in (oh, and since we're dreaming, somehow the grass would magically stay green and the perfect height with no mowing needed).
The beach would be within driving distance of a major city for all my shopping needs and the town would have a nice movie theater, a huge bookstore, a trader joes and a regular grocery store, and a ton (a TON) of delicious but cheap resturants. Oh, and the weather would be 70-80 degrees year round with no snow (except once a year on christmas), hurricanes, tsunamis, tornadoes, or thunderstorms (an occasional light rain is fine).
That's in a perfect world - I'd settle for just living at a nice normal beach though.
