Well - since I only have the one bike, it's the one I ride. LOL!!

I'd hate to lose it. In fact I'd be heartbroken. That being said, it's not that great of a bike so I can't imagine anyone bothering. I think a solid chain & lock (not a cheapie from walmart but a city one) left on the bike rack will work for me. These chains are way too heavy to carry in any sort of pocket or seat bag and I don't wear a camel or back pack of any kind. No need to really, nothing to carry. Well except a chain and thus we are back to the beginning.

Thanks for all the great suggestions.
