I lost quixote.com to a missed renewal e-mail and my being too cheap to pay the $20 fee for the expired domain thinking I could pick it up when it was released (in hindsight, ridiculously dumb). To make things worse, it was picked up by a Los Angeles film equipment company and for a while when I was taking grad math classes at CSULB, I would drive past a parking lot filled with trucks with quixote.com emblazoned on the side. It still gives me a little indigestion to think about that.
