Back in yesteryear, food was food. There weren't choices.......there was just food if you could find it. Wild, edible foods were picked with delight and thanksgiving. Blackberries were no exception. They were free, delicious, and could be eaten fresh, cooked, or made into pies, cobbler, jams, jelly, preserves. It took a lot of individual berries to make a gallon, but it was worth the effort.
Some of the hazards of blackberry pick'n were: chiggers (red bugs), snakes, thorns, and wasp nest, just to name a few. Most people tried to do their pick'n early in the morning while the weather was cool. A gallon of fresh berries would get a boy about 75 cents if he was lucky.
