Since many of the CA people like myself travel back and forth around this huge state as compared to going outside it, I think this is a good thread.
As for radar, we already know the two most used bands are K and Ka with Ka probably being used the most.
However, Laser seems to be more of a mystery.
Here is what i know so far of places/highways that use laser:
Fresno and Surrounding area (freeway 99, 41, 180)-I am stil awaiting an actual attack to verify
Any more specific info about the bay area or southern CA where laser is used?
