I just did....Go to the USDA web page, and email the secretary
yourself.....If he gets enough complaints, perhaps he just might stop
harassing those people........

Dealing with federal bureaucrats is an exercise in futility.
Virtually every executive agency in the U.S. government is
criminally corrupt.  Job one of all federal bureaucrats is
to protect their job.   Job two for a federal bureaucrat is
to line their pockets with public funds.  I worked several
years for a federal agency.  When I would not participate
in the fraud, waste, abuse, and other criminal corruption,
I was targeted as an outcast and for loss of job.  When I
complained to the agency inspector general, I discovered
he too was participating in criminally corrupt activities to
fill his personal bank accounts with taxpayer money.

One must realize, unimportant items like harassing the
owners of the Hemingway Museum in Key West are a
way that federal bureaucrats justify their existance.  Most
importantly, note how bureaucrats never target someone or
some organization that can fight back   The last thing a
federal bureaucrat wants to do is become involved in a
highly visible legal battle.  Publicity exposes their criminally
corrupt activities.

Congressmen?   Ha, forget it.  Involve them, and they will
send you the usual form letter and promptly forget you
exist.  Congress itself is full of corruption.
