On my recent visit to San Francisco, Rajan (Patas) Ratnesar hosted a dinner at his Castro Valley home on April 21st, 2011. I met R. Nadarajah there for the first time since our graduation in March 1967. The visit to Castro Valley brought back fond memories for me as I had spent two years in the San Francisco Bay area in 1974/75 when I was a graduate student at the University of California, Berkeley.
