Knower. Multiple-witness. Boatload of non-visual "events", some cautiously interactive. I found a track line in '74 and had my first sighting in '76, extended, unambiguous. I already took for granted that they were there, just never expected to see one. I didn't really do anything in the way of research 'til about 2007 when weird stuff was happening on a mountain I was trying to hunt. Trying to sort that out lead me to getting involved with a regional group about 2010. I'm deliberately not naming them. Eventually the group founder and I became like siblings. By 2015 or so I was investigating reports for the site and by 2016 or so I was assisting with forum moderation. The group had somewhat stagnated and I was unwilling to stagnate with them. I was providing most of the research reports, doing a lot of work, and not getting anything back. That was the situation when I went on the BFRO expedition ... looking for new horizons. About 2 years ago, the group founder and I parted ways on bad terms over political differences, nothing to do with bigfoot, but that chapter is closed. I've been researching one location since about 2007 and another since 2011 plus poking into other areas farther away as it fits into my time/schedule. I don't precisely "research bigfoot", rather, I do a lot of hunting, fishing, backpacking (with a significant amount being off-trail, cross country wilderness treks) with my senses alert. I run audio essentially full time. I watch for tracks when I'm hiking and fishing. There is a lot more going on than most people realize, it's just subtle, and yet there is also a lot less going on than some others claim .. IMHO.
I guess the short way of saying that is I was fairly well immersed in the topic, in the community, etc already.
