As to using generators while no one else has power...I don't think I would do it to run electric lights. I can see doing it to run the fridge, water heater, stove...stuff like that. But, yes, if your house is lit up in the middle of a blackout, it's going to look like the "Grail-shaped beacon". I'd stick with other options for lighting.
Something I need to do myself is either run a line from my detached garage to the house or build a generator box just outside the house. Either one should muffle the sound enough to NOT be too noticeable.
Great posts from those who have been through this storm. Keep 'em up!
