Day 16 - Philadelphia. I was speaking on a panel, talking about user-generated content at a Wharton Technology Conference. The night before the session, I had a free hour in Philadelphia around dinner time and decided to go to the very spot where I proposed to my wife. The Striped Bass is a posh fish restaurant on 15th and Walnut in the heart of the swankiest part of Center City, not too far from where we lived when she was at Wharton. The big evening four years ago involved an early seating, Opera tickets to Carmen later that night, a vase of orchids, a story, a Chinese character (double happiness), and a ring. It was obviously a magical evening and to reminisce without my wife seemed hollow. But the signature black bass was, as usual, to die for.
