USGA Private Jet Travel, Vol. 4

Regarding the USGA's private jet program and trying to understand the rationale for specific trips taken, the USGA's Marty Parkes says that information given to me by David Fay and posted here, "is what we're prepared to share." 

Parkes says there are "several valid reasons why such confidentially is warranted," though he did not elaborate on what those reasons are.

What is so sensitive about a trip similar to the Kennebunkport First Tee meeting that was cited? Or some rubber chicken golf association dinners?

And why would those require confidentiality when the USGA Audit Committee has evaluated and cleared them as acceptable?
