My daddy always told me there is no such thing as a fair fight. Either you have the advantage or the other guy does. So I'm just being prepared, I got a u-lock too. But if the other party has something more substantial, so do I. I learned the hard way, by getting a .44 mag shoved in my face for my car. Catch me slipping once, shame on me. Try that carjackin/bikejackin sh*t again and you get a hydrashock in the *****.
