Paul and Barbara Weiss went to Mexico in July, 2005 to give wheelchairs to those needing. The obituary which appeared in last week’s Palo Alto Weekly claims this was 2011. Did he go twice?

edit to add: Brian Moore commented on the Weekly’s obit page, which I was somewhat pleased to notice my Dad shared a column, and in the print version the page, with George Liddicoat, the father of my friend John Liddicoat:

Paul Edward Weiss, whose obituary appeared today, was a gentle, generous, and genuinely good man. He always seemed to have a slight smile on his face, as if bemused by life. It was always a pleasure for me just being in his presence. He made a difference, and he will be missed. (I made the point to Brian that my dad’s middle name was his dad’s first name, Edward Moore, and it stuck).
