For more than three decades, ABC Tree Farms have provided the Bay Area with seasonal fun September through December. Summer inspires the first round of recreation in the form of Summer Fun Zones packed with inflatable bounce houses masquerading as castles and slides. During September, they run 20 pumpkin-themed locations, some of which also feature inflatable bounce houses and other attractions. Once Thanksgiving passes, groves of Christmas trees spring up, having made their way south from Oregon and Washington. There they will stand until Christmas Eve, hoping to decorate homes or become the model that inspires a revamped line of evergreen air fresheners.
