My girlfriend's cro-moly shogun commuter that is about 10years old was stolen from the back porch of my house. It was left overnight so i figure it was someone just lurking about people's backyard looking for stuff to steal. Now we both have decent racers we only lock them up in the university bike lock-up which requires key-card access and is logged. If I ever ride anywhere i always bring it inside and will not ride into the city ever. You can't lock everything, think how easy it would be to steal someone's cranks and pedals. Alone they are worth more than 3 Huffys.
