If one recognizes the location of the State Patrol office in Eastgate it is not hard to imagine that there could be a lot of enforcement of speed limits in the area. In my experience, the most likely places to be subjected to speed monitoring are heading east on I-90 just beyond the 148th ave exit and al the way down the hill to Exit 15 - the first Issaquah exit and the exit to the State Park and to SR 900. I usually move over to the right lane once I pass Eastgate and just follow traffic speed all the way through Issaquah. I do think the absolute "best" place to get nailed is driving westbound into the Issaquah area where the speed limt changes from 70 to 60. So often there is a WSP car parked on the left side of I-90 as the traffic passes Front Street I'm thinking it might be confused as a monument.
