Every summer state patrol focuses on tickets by airplane. Heading westbound between Liberty Lake, WA and N Sullivan Rd. the airplane radio’s have well over 5 or 6 cars and motorcycle cops usually hiding on the west side of N Sullivan Rd. on the Interstate on ramp. Note radar detectors don’t pick up airial radar! Always look up in this area. Most days throughout the year you can find state patrol cars hiding out in this area ready to tax you with a speeding ticket. Also, unmarked cars frequent the area looking for their latest victim! They make lots of money here!!! 5 cars pulled over every 15 minutes ads up fast at a minimum of $120 per ticket this is pure and simple a speed trap for creating revenue!
