Its a difficult one - to all intents and purposes SM is closed to ALL G/A.
I understand that the "other side" of the airfield was only leased to G/A by the Army, and post 9/11, they took it all back.
There certainly is some G/A activity there, and a lot of military avaition activity, but I am sure that no civil aircraft are based on the airfield anymore.
I think it's a case of "who you know", perhaps "Formationphoto" may be able to help.
