The “Lind Speedtrap” is well known by those who travel I-90 from Spokane to points west of there. A WSP detachment is stationed out of Ritzville and loves to hide on the Lind, WA onramps and offramps. I was traveling SB to get onto I-90 EB to Ritzville/Spokane and came across 2 WSP patrol units, hunkered down and out of site from the Interstate – always wondered where they “hid” and just stumbled upon them by accident. I waved, knowing now where they hid – one trooper didn’t look too happy, but he couldn’t nail me for just waving. They must be the “spotters” and the “chase unit” is somewhere down the highway, or at the onramp EB to I-90. Do not go over 5MPH of the speed limit and stay in the right lane if at all possible. Once you get past that 20 mile corridor, you’re fairly safe, although I have spotted a Spokane County Sheriff’s unit & WSP while crossing the county line into Spokane County from Adams County, also another trap.
