LA169 southbound approaching I-20
On LA 169 at north corporate limit, in the woods about 1/4 mile north of I-20 exchange, limit drops from 55 to 45. Officer wrote me up for 60/45; my speed maybe 55 at point I started slowing after seeing sign and preparing to enter I-20 onramp. Fine $139. Officer driving a nice new car. Me: driving a 1995 pickup with Texas plates.
