Bike theft

Hey chaps,

I'm a student at Glasgow school of art currently working on a project to design a new way of securing a bike against theft.

I was hoping you could post a few stories if you had a bike that was stolen and what you were using to secure it at the time and if you now use a new way of securing it?

Or maybe you think you've devised a thief proof way of securing your bike.

Thanks in advance
