OK, who's kidding who?

In Northern Montana earlier this month, Pete and I found this sign posted on a waterfowl production area (WPA)...

I assume that this was not posted prior to the "Government Shutdown", since it was not known that this would happen until it did, in fact, happen.

So... with no money to operate, the federal WPA management found the funds to print signs, purchase gas and drive US Govt trucks around posting all the public property to deny public access. With 'volunteer' agency personnel. And then, they found 'volunteers' to burn more fuel in government trucks driving around to patrol the grounds, keeping the public off public lands.

So who is kidding who, here?
