[ZOA NOM]

Holy crap, a homemade VASI? I'm really surprised the FAA didn't do something other than have you issue a NOTAM. You could kill somebody if that VASI isn't aligned properly. Hopefully, he was somewhat competent with it's installation. Is there a neutral neighbor that could take the lead and have a civil discussion with the guy to give him a way to air his grievances, or at least confirm he's nuts?
