I haven't been to the airport in a few days, where is the aircraft parked? There are several ramp areas besides the commercial/private area. If the aircraft is parked near the private aircraft hangers you might try stopping at the office building at 4955 E. Andersen Ave. That is Allegiant's operations office and they might be willing to help or walk you around the aircraft.
Security will be higher the next few days so I'd personally be cautious about any shots that need to be taken near the military facilities which surround FAT
or with the military in the background. As long as you follow Flygga's post they may question you for a few minutes then ask you to leave.
Besides the 144th ANG F-16 base there are several other spots to be aware of that could be highly guarded. Along Dakota Ave there is the Army National Guard Aviation Unit and also the Calif Highway Patrol hanger. Most sensitive are the rounded earth bunkers near Dakota Ave. where the military stores various items. There is also a Marines base on the north side between the golf course and Skywest.
BTW CV990, I hope you've had the chance to link up with some of the Portuguese groups in the area. California is mainly Azorean immigrants but we're entering Festa season with something happening in a different city every weekend. Plenty of sopas and other food combined with music.
