I have noticed lately that most of the big rigs are doing the limit which is 65 here. They used to do about 70 or more. Cars, trucks, and SUV's on the other hand apparently don't care about the price of gas, they still run 75 plus. I travel 17 miles each way on a 65 MPH road, I drive at 65 and never pass anyone. They fly by me at 75 or more, get off at the same exit (where I catch up to them at the red light) then they go to Wally World. I really don't know what there hurry was. They prices in the store don't go up till the night shift comes in.
