Each of us is different. In my own case, my titanium frame mountain bike has value - probably more than my car, to be honest. But much more than that is, this bike has special memories and meaning to me. She's a real special memento of all the places in all the states we've been together. I don't suppose many people have possessions that have special meaning anymore.
But I can tell you this: If she went missing, I would go crazy trying to get her back.
