I put in the effort on here first, getting to know people and reading everything I could. Then when I had absorbed everything I could I took what I learned to the woods. I have seen one, I have heard them numerous times, and I have traded with them to boot. Over the course of a year I have had at least a dozen solid experiences with these creatures. It is not impossible to get experiences with them by any means unless you are not open to information, which is what I see all day long on here...people not open to information, running around demeaning and talking down to others on a daily basis when if they were really interested and sincere they would be spending their time learning and putting the pieces together instead. Everything you need to work with this subject is right here in abundance.
These things run fast, they take things from you that nothing else ever would in the woods, they make sounds no other animal makes, they talk, they thump and knock in the woods constantly, they work together to avoid you, and they throw things. Pretty easy to put that stuff together if you study up. I have read over 10,000 reports, listened to weeks worth of blogtalk radio, gotten to know dozens of researchers, and spent thousands of hours out in the field. The best I get is having activity about 1/5 times I get into the woods where I am at, it took me over a dozen other locations before I found this one and I regret none of the blood and sweat spent to get where I am now, it is by far the most exciting and rewarding undertaking I have ever done.
The key thing to me(Besides not being afraid), atleast with the ones where I am at, is the knocks and thuds. Not real "uncommon" that you hear a vocalization, sometimes a giant raven or a hollering woman sort of deal, but it is usually just for a few seconds and it is done. The knocks and thuds though, that is the key when out in the woods prospecting for a new research area, do your own, I personally use the back of my axe, and then listen for others. Gotta listen to every sound that goes on in the woods and think of what it is or you are gonna blow it.
