My Vietnamese buddy has a taste for not quite ripe fruit. He said in the old country everyone would come steal your fruit as it ripened. He who could stomach the greenest fruit won.
I've got a similar problem with chipmunks and the Marian plums I grow. The chipmunks start raiding the trees when the fruit just begins turning yellow and becoming fragrant. But all they do it take a bite and throw the still somewhat green fruit on the ground.
Cheap Chinese pellet gun is cheaper. I'm sure chipmunk will work nearly interchangeably with squirrel in most recipes and arguably would be a little less white trash.
Ha! I lived next to Vietnamese neighborhood in San Jose in the 90's. Never got to taste the fruit on my trees; gangs of kids would come along a few days before it was ripe and boost one another up and take all the almost-ripe fruit.
