We live in leafy (other adjectives are available) Morningside. We are lucky enough to have a front garden and room for a bike shed in said garden. It's right by the front door.
At some point last night our bike shed was assaulted. Somebody unscrewed the hinges on one side of the double doors to get into the shed. Inside the shed is approaching £2k's worth of unlocked bikes. They didn't touch them. The only thing that appears to have been taken is the eight screws that fastened the hinges to the shed. Exactly the same happened to our neighbour two doors up.
So, it seems we were lucky. I'm off to buy some one-way screws...
