What a great experience for you.
Let me tell you about a experience I had. We have a so called expert here locally. I asked him to show me the ropes on coyote trapping and snaring. "Oh I sell classes to do that". This is the same guy who latter told me there are no coyotes left in the SW Ohio area, and my muscles would break down if I used a heating pad on them.
OK I got this figured out and never did take his classes. LOL.
