We consider some of the fundamental statistical mechanics of the electrodiffusion of a long polyelectrolyte, DNA, in a microlithographically constructed 2D rectangular array of cylindrical posts. The DNA polymer is shown to be free draining when not hooked on a post, and the mean time to unhook is explicitly calculated and compared to our measurements.
