I know the feeling...lust is a beautiful thing. I have three road bikes--my "main" bike, my backup bike (for when the main bike is in the shop, for use on the trainer, and in really lousy weather), and my Florida bike (my in-laws have a winter home in Florida and we travel there 2-3 times per year).
I know, I'm bad. But we are DINKS, and it's truly my only vice.
