I like having beater commuter bikes that I can lock up anywhere. I have two-an old trek mtb covered in very obvious stickers so it won't get stolen and a rusty steel frame fixie that I just adore riding-but I don't have a secure place to put my nice bikes, so I'm forced to ride the bad ones.

If you like your road bike, ride it! But I personally like my beaters for the peace of mind that I can lock them up anywhere and noone would look twice at them.
