the police are there a lot on any of those blind corners...so the radar detectors do come in handy in this atmosphere...as for the trucks...well...a nice big warning sign close to Marysville would end that...but I quess no jurisdiction cares. So, their gps will take them there if it is set on "the shortest route"... Now my trucker gps I used last year, took me out of the way and tried to bring me in to the lodge from the south. I missed my usual turn and took us out of the way not realizing I had not changed over to a "car" setting... so the newer software is taking you away from the Dragon...once I changed over to car settings, we found our way back to the lodge, after some detouring...lol...
