Can someone please explain the difference between the various organizations seeking donations on behalf of the Academy? There is the AOG, the Endowment, the Rando Fund, the General Fund(?) and even the Denver Airport USO to name a few. I want to donate and support the Academy, specifically programs and activities that support the cadets, but I'm getting calls and letters from each group asking for money. Can someone please provide a synopsis on donating to the Academy? Thanks!
