Sara says I can have anything I can afford and I haven't won the lotto yet. If I really want something she normally says things like "Great, you get an engine part and I get a basement under our 1920's house". After I did some research it seems like a fair trade to me.
With some planning and careful wording I have talked her into making our garage 4 times as big (2500 sqft') so we can "have a place to stay while the house is raised in the air". When what I really want is a huge shop with central air and heat with sleeping quarters, kitchen and bath.
Beat that! We break ground in the spring.
