Mine is sorta a combination of things. I've been referred to as "sasquatch" or "bigfoot" for many years by friends. So when I first joined a PA fly fishing forum, it seemed natural that my screen name be, "The Sasquatch". Then, many of my fly fishing buddies started referring to me as "the reverend", "reverend 'squatch", "reverent Sasquatch", etc. This is due to the fact that as long as some of them have known me, I've been in college and now seminary pursuing "the ministry". I'm not a "reverend" yet (just a pastoral intern), but the name kinda stuck and I kinda liked it. "The Sasquatch" was already taken on this site, so I went w/ reverendsasquatch.
The avatar is a fly fishing sasquatch. Self explanatory.
