Unfortunately space and $$$ will always hinder this dream.
Since I don't have a basement to claim as my own, I have to make due with the space I have now.
Now, if there was some kind of *cough* "Natural Disaster" *cough* that befell the back of the house. I would be forced to expand the patio into a 16' X 28' climate controlled oasis of pinball goodness...
I sure hope nature is on it's best behavior in 2012...
