FF is completely correct and is how AOPA operates. That is the reason so much work is done by volunteers.
Anyone is free to volunteer and AOPA welcomes all offers. Through the hard work and efforts of these volunteers GA has benefited significantly for decades.
The accounts of the organisation are freely available to members. Any profit made on merchandising etc is poured straight into the organisation. There are no leaches taking money out of the organisation. What goes in is used to represent you the member. I go through the accounts every year and am satisfied with the transparency and use of the funds that I contribute as a member.
There is nothing cloak and dagger about the organisation
