Even though I think that the IMAA no longer serves any usefull purpose I will keep my membership simply to fly in the few events that I like that require IMAA.
At the dollar level that they operate on the yearly dues amount to less than half of a prop or even half a tank of gas to get there to break a prop.
I am sure that it is the principle of the thing but if I am going to stand on a principle, I want it to be a much larger one than the IMAA.
