I once bought a bike for my daughter from a CL seller in the middle of a workday then rode 7 miles back to the Park and Ride where I had parked in the morning with one hand steering the "new" bike. I've seen guys do that taking their pit bike to the pits at CX races and they make it look easy, but I had a heck of a time with it.

As for N+1, it's been nine months since I bought a bike, and I gave one away a few months after that so it really doesn't count, right?
