Bigfoot and rainfall

Written by Richard Noll
The Pacific Northwest, actually the greater Seattle area, is fast approaching a record rain streak. It stands at 33 days but on this coming Friday that could easily be exceeded. Forecasts predict at least another 5 days to the continuous downfall we are having. I mention this for two reasons:
1. It has been mentioned by John Green, "Sasquatch: The Apes Among Us", pg 170-188, Chapter 10 - "Twenty Inches of Rain", that one of the only patterns he has seen with the data he collected, which had the most stringent validation process attached to it’s collection in my book, was that reports seem to be tied to areas with 20 inches or more rainfall per year, and
2. My laptop went down and is being repaired. All the postings I was working on are in it and I won’t get it back for a few more days yet, so I thought I would poll the readership here in the meantime.
What is it about the rain that a pattern appears in Bigfoot reports? Does it have to do with thermo-regulation? Food resources? Mineral leaching? Maybe they have to come out of the ground, from their hiding places, for fear of being flooded out? Just kidding on that one.
I have my own theories but I am really interested in what all of you think about this so please comment on the phenomena within the phenomenon.
