I had a buddy who was an Italian spec ops dude that would shore up income by hunting for truffles- He used a dog not a pig.
I was effing shocked at the prices paid for that.
He said it was the best part time job ever- he'd go out in the woods with his dog, dig stuff up, come back and sell his 'catch' for thousands of dollars.
basically he got paid big cash for doing a nature walk.
Only thing I have hunted in the woods is pig, elk, deer, turkey and Shrooms.
When I was a young lad the best shrooms in middle Georgia could be found on the pastures of the sheriff for the country next to ours.
We never made any money off it but certainly took some trips.
