I always leave leave my lock at work on the bike rack because it is pretty heavy. Everywhere else I am going, I am not leaving the bike alone. Never. I have learned this the hard (and costly) way. It is either home, on the rode, or in my car (it is a folding bike.) All scenarios made sense except the one regarding eating because I didn't find any teeth remnants on the floor lol! Thank you so much for your consideration and answers everyone!
