Why doesn't a group like PSIA start the lobby process to gain access for (defined professional) instructors to "any mountain ski resort that is leased on state or federally owned land". Perhaps each area could "test" applicants to individual areas, but any site-specific tests would be negotiated & administered by the PSIA.
IOW, any resort on government land could not prevent a certified instructor from advertising & conducting classes and private lessons on the mountain, so long as they were trained not to be an obstruction to the facility.
1.) I'm serious
2.) there have to be a few annoyed high powered attorney PSIA members with law firms who could set a few associates to the task.
Hey, it works for the aircraft industry, among many, many others.
