1. Did you use a bike rack?
2. Did you have the bike parked in full view of everyone?
3. What lock did you use? Chain, U-Lock, cable?
4. What brand of lock did you use?
5. Did you hide the bike behind bushes, Dumpsters? etc.
6 Where did you place your bike if it was not hidden or attached
to a bike rack?

I know it sounds like of silly but more people can learn alot from your experience. By the way, I hope you find your bike.
