Blow molded fencing system

Abstract

A fence system including fence sections including singular blow-molded pickets that engage with fence rails using no additional parts and wherein the pickets show no external signs of functional engagement between the pickets and fence rails (e.g., pickets having substantially planar surfaces common to traditional wooden picket fence designs).
