What is accomplished by not having a sign that shows where the road straight ahead leads to?  Sure, it’s weapons grade plutonium processing facility and nuclear power plant.  So what?  Anyone that might be interesting in attacking it is going to know that even if there isn’t a sign saying:

Nuclear Plant Ahead
Proceed with Caution
Snipers at Play

  Whatever.  It still makes me smile every time I drive by.
