Sorry I wasn't clear about the letter of agreement. Yes, it is
between the FAA and three local soaring organizations - two FBOs and
the ASA.

Estrella is apparently going very well with a very solid training
schedule, but it is starting to look like it will be encroached upon
within the next few years. Furious development there has ended with
the recent housing problems, but there will be pressure as land sales
to developers are continuing. What makes me more pessimistic is that
until the recent changes the FAA had been receptive to protecting
Estrella's airspace. Now they don't seem to care.
