Thanks for the input on that…it is so interesting when you are the student, and the instructor, you get to see the difference a lot when you are doing it, and someone is observing. As for the digging, not sure the truffle was on the other side of the bush, he was digging at. The truffle that was there was over a week ago…not sure if the scent would linger that long… I was thinking of doing a new location in the front yard…I do have a forest behind us, could try there as well, he has done some search and rescue practice there when he was younger. I would of course make it very easy for him. It is also a known area for him. Thoughts?
