I searched the 2001 & 2004 WBCCI Membership Directories (don't have 2002 or 2003) and found 4 Carmichael's listed in each: two in VA, one in FL, & one in CA. The Directory records Caravan's that WBCCI members participate in, but none of the Carmichael's are noted as having participated in a 2003 Lighthouse Color Caravan. Sorry.
