Bike Vs Metro

I am going to keep a running tab this summer on how much my bike costs me. Although the joy I get from it is pricelss (or about $5000) I am betting right now that I will put in more than the bike is worth ($100) or even for that matter how much a new decent bike would cost me ($250). I will also be keeping a running tab of how much I have to spend on the Metro when my bike ultimately fails me leaving no other option that public transportation to get to work.
The running taly will be kept in the comments.

So thus far I have spent:

$10 on a new inner tube for the flat back tire (April 12th)
$12 on metro tickets to get to work this week
$6 new inner tube (april 29)
$25 New tire and new inner tube (June 13th)
$51 New rim, hub and inner tube (July 28th)
