I think Mar 05 is the earliest you will see as BWE got hacked around then and everything was reset.
I think the original board was put up 2001 or 2002 similar format as the Kayak Sportfishing forum

Allens kayak in Mission Bay ran Yakfishing.com message board and Jim's site Kayak4fish was up around then too.
I remember my first postings were on the now gone Buddy Boaters Board in 1999 as I was already on there as a PBer...........turned kayak fisherman
