i live in cincinnati ohio(just moved), so if anyone knows a specific place here, thatd be great. other than a specific place, where exactly do you go to weigh your car?
Truckstops have scales -- but they will charge you. Probably $7.00
Never tried a scrapyard or dump -- they may do it free, not sure.
My personal preference is to find a closed weigh station on the highway. Usually they leave the scales on. You won't get a printout, but you can drive on and check your weight either on a board outside or by looking in the booth.
I checked mine on an electronic grain scale back in IL. They are accurate to +/- 10 pounds. I just drove it on there and peaked in the window at the readout. The one I used was dead on because it caculated my body weight exactly.
