Yup. I have such distrust for the public, I've never even owned a bike lock. I never ever take my bike to a place somewhere where I have to leave it. I do rides for fitness/fun and then come home. That's it.

I would love to be able to ride to friends places but if a thief would steal a $50 bike, of course they would try to take my $600 trek.... yes I'm paranoid. Not afraid to admit it freely. I hear such sad stories of such nice bikes being stolen, it's terrible.
