I think a deep breath might be in order.
If Joe has had experience with hunters, who one would expect would be pretty sharp with estimating range and size of animals, misjudge these things, there is no reason to let feelings get bent out of shape when he points out that it might have happened in this case (because it can and does happen). Compared to Joe, practically everyone living in the UK is town based.
Looking at a map, I am not sure I would call his location "fortunate". For example, Thetford is about 35 miles from Cambridge and I am sure there are some nice camera shops around there, where-as the nearest photographic related shop to Joe looks to be about 9.5 hours away! Pros and cons!
I was going to mention the photos of big cats that are actually just house cats without a recognised frame of reference.
Over the last month or so I have been watching some videos on Youtube from Steve Isdahl Howtohunt. He has a lot of stories and is good at telling them. He lives in British Columbia and has a lot of Sasquatch related stories. Watching the videos and reading the comments is interesting in what it shows of how people respond to unusual experiences, and how other people then respond to hearing about them. Steve mentions how many people tell him about seeing Sasquatch, but have not told other folk because they don't want to be ridiculed. They see stuff, and keep quiet. Some sceptics are down right rude, but even when they are not, things can quickly deteriorate when what one group thinks of as healthy caution taking a stranger's story at face value and thorough examination of all possibilities, the other takes as a personal affront to their honesty and intelligence.
I hope you will consider posting any other unusual sightings. I may be a septic by nature, but I have learned a fair bit as a result of this thread, so thanks for posting it!!! It would be a boring, and unhealthy place if everyone agreed all the time.
