The 30th reunion was

October 11, 2003

To see (and buy) portraits and candids taken at the event, go to http://www.jwpartypictures.com. Then, on the left, click on "Great Reunions". Then, at the next page, click on "Click Here for All Events". Then, since CV doesn't show up on the first page, type in "Crescenta Valley" in the little FIND box on the left. You'll get there eventually. As a shortcut, try typing in (or just clicking here) http://www.photoreflect.com/scripts/prsm.dll?EventFrame?event=02TL00II
Those last two characters are capital "I", not one-one. That will get you to the portraits.
The candids appear to be at: http://www.photoreflect.com/scripts/prsm.dll?EventFrame?event=02TL00IH
This may not work later, but it worked on November 3, 2003. Give it a shot; it will save you a lot of typing and mouse clicking.
