Having had numerous bikes stolen by several amazingly determined individuals, each one overcoming newer anti-theft obstacles than his predecessor, I gave great thought before I decided on a concise reply:
If you can, park your bike in your kitchen (floor's easier to clean) and leave the light on. I once parked a Bianchi in a rented garage and, because my neighbor couldn't be bothered to shut, let alone LOCK, his garage door, I lost a bike which was chained to a support member.
My current bike is in a windowless shed behind a locked steel door. But if I thought my wife would let me, I'd keep it in my kitchen. Not far from my crossbows and knives.
