Padilla Hts Rd South of – and under – SR 20 bridge, and West of traffic circle. Speed posted at 30 MPH by a very small and hard-to-see sign just inside the Swinomish Reservation boundary. Swinomish Tribal Police operate a readar trap near the sign. No warnings if speed is 10 MPH over limit. (Rationale: "They’re getting ready to build a Wal-Mart here, so we’re trying to get people used to slowing down.") Normal speed limits elsewhere in vicinity, by the way, are in the 35 – 40 mph range.
