Arrange to have some scaffolding erected over the bike racks.... One
of the contract scaffolders at work cleared half a dozen unclaimed
bikes in under 5 minutes (whilst the rest of the crew were still
parking the lorry). Don't know the technique in detail, but he was
fast. I believe he may have used 2 lengths of scaffolding pole to
lever the D locks though... It brought home to me the fact that most
locks are just for show.
