1. A signpost connector for use in coupling a sign support to an anchor, said signpost connector comprising:
a plurality of connection plates each comprising a set of openings that align when said connection plates are oriented relative to each other; a plurality of separate washers selectively positioned between said connection plates, wherein each of said washers is U-shaped and has an elongated slot selectively positioned in alignment with aligned openings defined in said connection plates; and a plurality of slip bolts for coupling said connection plates together at said aligned openings, wherein said slip bolts enable the sign support to separate from the anchor when at least one of the sign support and said signpost connector is impacted with a separation load, and wherein said elongated slots are selectively oriented inwardly towards a common central axis to facilitate causing said slip bolts to slip out of said aligned openings in response to the separation load.
