Advantages to keeping old road bike after getting a new one? (medium-length)

[Mr. Bloom]

Yea! on getting a new bike!

I still have my first road bike (trek 1000), but it was not really "sell"-able because it was wrecked but still ride-able.

I like having it for bad weather rides, back up when the other is in the shop, a bike to share with a friend (of a similiar size). I've gotten a little playful with it by doing things that I wouldn't do to my "real" road bike, like putting silver streamers on the handlebars

Hmmm...she didn't mention the biggest advantage.

The advantage of keeping your prior bike:

So your spouse/significant other (aka "SILVER") can scavenge the components for her bike
