Strictly Enforced

One of favorite signs to see along the road is the "strictly enforced"
sign. It usually contains some trumped up promise meant to make you
believe law enforcement personnel are strapped to every other tree,
two fisting radar guns that are pointed squarely at you. What makes it a
puzzler is that the signs rarely list the speed limit they are
strictly enforcing. 20 square feet of signage and they can't find
room for a measley "35"!
