Amstrong County Deputy was sitting a first reduction coming into town. Drops from 75 mph all the way down to 30 mph. First reduction is from 75 to 70 mph with no advanced warning. Four lane divided Highway with signs only on right side of road, I was screened from signage by Semis and Motor Homes. I know ignorance is not an excuss but if signage had also been on left side I might have been able to comply. I had cruse set at 77 mph, officer said I was doing 84 mph. Since I missed sign I looped back out to verify location and the officer already had another stopped by the time I turned around and came back into town. If you have had a similar experiance vote with your pocket book and word of mouth. Boycott all Claude Businesses until these tactics change, tell your friends to do the same. Beyond that my experiance match those of other drivers repoting on this site
