Jeff-
Sorry for being late to the discussion. To borrow some verbiage from Ron W... "You stated your case well, non-emotionally, and with good logic.". Interesting point about the volunteers. Here's my logic, open for debate, obviously....
As the core EAA members' age increases, the 'honey pot' of free labor for OSH is evaporating (absent an influx of new volunteers/members). This means fewer folks to accomplish the basics (setup, parking, registration, etc, etc..most of us know the drill and have done it).
During the same time period, EAA HQ is increasing the overall volunteer labor needed by adding more...I'll call it a 'general admission' factor.... with concerts, T-Birds, etc. Seems there's got to be breaking point somewhere.
It's said regularly that EAA makes most of it's money at OSH....the volunteers would seem to be a major source of that funding. Will that continue if AirVenture continues to go more mainstream?....just askin'.
