When I was in high school I worked on a project with a meteorologist from Rutgers University studying the phases of the moon and whether there was a correlation between them and frost. This study was done in relation to the peach farmers in Southern New Jersey. There is a huge area of land there that has peaches. You might want to check to see if there were shipments originating there. My conjecture would be that it was mainly shipped to either Philadelphia or New York City.
