I had been pondering the idea of starting a "neon letters" collection for some days. One day (evening) as I walked home from work, I started shooting a few. It occurred to me that I should pay specific attention to uncommon letters; I would surely get the common ones anyway. Then just at the very moment I was thinking about how rare Q and Z might be (they being the most valuable Scrabble letters -- North American Scrabble anyway), I noticed I was approaching the Queen Elizabeth Theatre. Magical! (P.S.: Z is actually somewhat common, because of pizza.)
