Back when I went climbing every weekend, we stopped at a convenience store on the way. They had "norsk" car air fresheners, which struck us as funny because "norsk" was fun to say, and for the rest of the day we said it many times. Anyway, that evolved into my username. Avatar is just a cool vintage track image I came across, I like old track bikes!
