Well, it certainly appears to be discriminitory, and probably could be
challenged. Probably SHOULD be challenged, lest Bill Gates and friends get the
impression they can shut down any airport they choose, just by virtue of their
being there. The whole system is heavily subsidized, and the subsidy is
predicated on equal, unprejudiced access to all legitimate users.

I can understand the predicament of the airport manager, and it includes a
security concern, because a gathering of VIP's like this is almost as much of
a lighnting rod as a gathering of political heavy-hitters. Nevertheless, the
airport should make an effort to accomodate all users - and this includes
asking for volontary limitations from VFR and training activities, rather than
just hanging out the NO VACANCY sign.
