Will there be a 'daily double'?
Over there, you have 'The Centre for Fortean Zoology' (CFZ). Paul Vella ( RIP 2017 ) was the CFZ Bigfoot Study Chair. He was a member of several Sasquatch websites. I do not know what kind of Sasquatch files that the CFZ may have.
I would recommend visiting www.bigfootencounters.com. The site was started by 'Bobbie Short' who passed in 2013. Her grandson keeps the site up but it is not current. Lots of reading there.
Bobbie Short was working on a book when she passed. Friends and associates finished the book. The book, "The de facto Sasquatch" is available in 2 downloadable pdf files.
On the site, the right hand margin has many selections. Go to the top one, "What's New". The first 2 paragraphs have the download links for the book. The downloads are 406 & 157 pages.
"The de facto Sasquatch" may be your cup of Earl Grey. 563 pages is a lot of reading to stare at your monitor. I suggest downloading the pdf files and have 'Old Timers Cameras LTD' aka 'OTC Ltd' print and bind them. They are in St Albans, UK. I have my camera manuals printed and bound by them.
Please keep us up to date about the 'Grey Man'. The UK also has strange weirdness occurring at nuclear power plants.
Cheers.
