Back when I was at Stanford a decade ago, I spotted him biking to/from Green Library quite a few times. You can probably run into him with some regularity if you make a habit of going to said library, assuming his routine hasn’t changed much ;)
Oh thats a cool fact to know! Thanks.
Somewhat recently we spotted him at a Hitchcock movie festival at Palo Alto, which my wife and I were attending.
Random run-ins are surreal :-)
