I'm laughing out loud at your post. It's so true. I guess I'm lucky (or maybe not depending on how broke I am) that my SO is equally obsessed. One of us buys something and the other needs one too. We feed off each other. I don't want to think how much money we've spent on biking gear this year. If it equals about $1 / km, then it's money well spent....

Good luck in getting her addicted though - it's nice to have something active to do together...
