Can you really have to much security for your prized possession? Never assume what someone else is thinking wherever you lock your bike up.

I recently had my saddle stolen and when I locked it up at our local university so I could use the library. The bike was only unattended for two hours and the school was on holiday (not many students) and is pretty isolated. I've parked my bike there many times without incident, then one day, something happens.

Basically learn from my mistake and secure as much as you can with what resources you have.
