I think this was back in the early 70s and if I remember correctly, there were several years in a row when there was very little mast crop. I don't remember the mushroom situation. There always seem to be apples somewhere unless there was a lot of damage to blossoms in the spring.
I do remember that year not seeing many big racks around that area. You could always count on the Bennett boys to find the big ones. They would sleep out on mountain tops for days at a time tracking the big one.
