Just an aside.
Some months ago I was looking for an airport or airstrip to place my aircraft should I eventually finish it. I visited a number of places one day, dressed reasonably casually, in my new car and carrying what notes I had researched in a folder.
In each of these places i just waltzed in looking for the boss or someone in authority, etc. to talk about hangars.
I came across about half a dozen people here and there working on their aircraft or just spending the time of day gas bagging.
I found it strange that in each case I was initially viewed with suspicion and fear - I could see it in peoples faces, starting with the guy changing a tire on a Jabiru.
I have just understood why that occurred - they were afraid - afraid I was from CASA.
