In June 1995 my older son moved from our home near Philadelphia to Berkeley, California, so he could begin graduate studies at UC. He and I drove across country in our van loaded with his things. We arrived in the Bay Area in the morning, unloaded at my father's house, and soon set off for Berkeley to find my son an apartment. No sooner had I turned onto Telegraph Avenue -- one of Berkeley's main streets leading to campus -- I saw a Penn Computer Science graduate student, Anthony K.! I was 2800+ miles away from Penn and quite unexpectedly I already saw someone I knew.
