You could have multiple bikes?
I have my "proper" (read expensive) roadie - which NEVER leaves my sight except at home, and then I built the fixie up myself, but because its a hodgepodge of different parts (most of them v. nice) on a scratched old frame - It looks much less valuable, and I'm much happier leaving it places. I think its the mash up of colours that does it :p
