As you see it's a common problem particularly if you had a yen that couldn't get scratched when you were younger. Now a $100 Klein or Cannondale st or a $25 Peugeot with aluminum wheels is just too much to resist. I fix and sell the ones that don't fit me and that helps with the financial side so the cost isn't an issue. Of course if your wife moves out because she can no longer get to the bedroom, that can be a problem. Parking the cars outside because there's no room in the garage is an early indicator that your headed for trouble. I'm at nine so I'm obviously a piker compared to most. Renting a storage shed can be a temporary fix but beware of the feeling that now your free to get more bikes. I find it hard to resist a great bargain and occasionally manage to go weeks without checking CL, "just for the fun of it," but if you spend time returning them to the wild or riding them then what's the harm?
