Examine the following clause by a site manager in a certain USA place:
"Pilots who wish to fly the site must be current ___(org)____ members. Visiting pilots who are not members will be able to purchase a 30-Day ____(?org)___ membership after arrival."
There is a severe tilt in the phrasing. Let's overlook the "wish" and let that mean more than wishing, but explicit flying. So, a pilot of a HG does fly in the airspace around "the site" but does not take off and does not land using land that is managed by the involved land manager. Such a HG pilot does not have to have membership in the implied "org" to fly in USA appropriate airspace. The land manager is stating more control than is necessary. The land controller might have phrased the matter: "One who takes off or lands on our controlled land will owe a certain duty or respect."
