Last year the population of squirrels was low in this area. Not one corn field with in a 1/2 mile of my woods and the Acrorn crop was poor and Hickorys there just were no nuts.
It was so bad I joked with friends I had to stop one day as a whole big old group crossed the road going to thr corn field a mile down the road much like the OKIEs during rhe dust bowl years.
this year corn all around my place acorns aplenty and Hickory nuts so thick it is dangours to walk any where near a tree because of the round footing.
Last year I could get a 5 squirrel limit in two days, this year 5 are a 30 minute sit in one spot.
