 After several farms began to sell apples individually to visitors, along with homemade apple pies, fresh apple cider and delicious apple butter from roadside stands Oak Glen became an apple boom town overnight.The export trade has since virtually disappeared, and growers now earn much of their revenue from visitors who are allowed to pick the apples directly from the trees to insure freshness and the best quality.Today many of the heirloom varieties still exist today even though many of them have been since lost in time.
