Catoosa, OK used to be infamous in the late 1990's. It's on Rt 66, and back then thry would stop you for any reason they could make up. It became a large enough problem that businesses started to leave, because neither customers nor employees wamted to risk driving there.
Something happened around the mid 2000's, and the police became lesa crazy. Since then the town has exploded in size.
I changed the oil in my Leaf a couple of weeks ago. It has a reduction gearbox that holds a couple quarts of transmission fluid.
