stolen 1992 Bridgestone XO-1

Bikes were stolen from my shed, which is on my deck in front of my door. But both deck & apartment are in the back of the house, up the stairs past my neighbors backdoor, & finally over a raised bridge above the driveway. Very removed. Someone had definitely prior knowledge that I keep bikes in a shed, which I do not always lock. My neighbor across the bridge said that her dogs heard someone at the back door around 6am today & she assumed it was me. The shed door was closed and the padlock was through the handle, but not latched. I have a lot of stuff in the shed, much of it has resale value. All they took was the bikes. They clearly knew what they were looking for. They also must have known that though my dog is big, she is not threatening, because it's unlikely they could have seen the whole setup without seeing her, as she is often outside.
