At Spring Fling, CHP brought out a display... why?

I dig the 70's Mopar cop car... and that it was a magazine feature car for it's impeccable restoration.. but why does CHP show up to a car show? They aren't the friendliest bunch on the road... just ask anyone who has ever been pulled over, been caught in a traffic jam and been redirected around a wreck, etc etc Why come to a car show to try recruit new officers?
