Hi Randy,
There's a page on the IRCA aka FI de CA #111 on the revived Sundown & Southern site I did. Mark Valerius, Michael Lumert, Steve Peck, etc. will probably be able to tell you more; but here's a start.
I really enjoyed my visit out to the SPCRR site at Ardenwood a few years ago after years of procrastinating getting out there. One of your volunteers ran by the Los Gatos Museum when I was volunteering there for a day and handed me a little flyer. Picked the right weekend and saw "Deanna", too! Keep up the good work.
