I don't remember the exact order of events any more
as to which came first,
but I think the first thing that happened was that UW Protection and
Security, as they were then named, did manage to notice us, and a woman
officer questioned us. We explained the arrangement, and she took down our
identities, but, somewhat understandably, wanted further proof of the
arrangement.
Heh. When I was at Caltech, the director of my lab gave the security
folk strict orders that I was not allowed to bring any of my junk
*into* the lab on weekends :-).
