almost all wildlife used to fear us - they now sense we have evolved into pushovers
Black Sucker-fish run up the streams every April in Wisconsin. He would net out enough to fill five burlap feed sacks. About 700 pounds. His wife pickled it and labeled the jars as "pickled herrring".
With proper planning one never needs a grocery store if thats how you like to live. He was very good at it.
Squirrels like nuts. Maybe that is why they are attacking?
