Ninja Bikes?

[Joey Shabadoo]

Why is it that many bike shelters and railings have bike locks attached to them but no bikes?

Have the thieves nicked the bike and somehow left the lock behind?
Do some people forget their locks?
Are the bikes subtly camouflaged and I'm not looking hard enough?

A lot of people leave their heavy D-lock at work/their place of storage.

I've got a D-lock permanently at work and so have many others.

Me too, I've better things to do than lug a D lock about I lock bike to same place every day so it makes sense to leave lock there
