I'm truly sorry for your loss. I hope someone finds it and returns it to you. But that isn't likely to happen - sorry to say. What I recommend is to have a good "beater-bike" to run errands on - with a very good lock nonetheless. I have two beautiful, custom machines. I'd never take my eyes off them and wouldn't think to leave them locked at a mall. Such is why I went and got a nice, used 3-speed war-wagon to haul my groceries and such - with a Kryptonite U-Lock in my cute, little wicker-basket.
