I once had more than four bikes...road, beater, xc, comp xc, comp trials, training trials, beater trials and a vintage trials bike.
I have only a road bike now, and a mountain of frames.
I really miss trials.
One of my good friends claims that having two children saved him money. He says it wasn't until his twin daughters were born that he was able to finally kick his drinking habit--a habit that was costing him ~$500 a week.
