Boy you're lucky.

We're on the side of a (small) mountain. The flat part of town is sunnier (we're in a redwood grove so it can get dark), and the houses in the flat part of town were way over our price range when we bought 2 years ago (million dollar tear downs). But... the flat sunny part of town floods, and has flooded several times this year.

So as long as our house stays attached to the hill we're doing okay!! (Although I don't feel comfortable letting our daughter ride her bike down the 14% grade that goes from our house to town yet.)
