They just came out with these new things called sheds, tents and a canapy. I hope you were kidding.
You gotta be kidding me, did you not read the above discussion?
If a storm is that weak that it won't flood the generator, then it's not strong enough a storm to cause an outage in NYC. Perhaps you live in some hickey town where every other rain shuts off the power... In NYC, it's only something strong a-la-Sandy that can cause widespread outage. In such a case you can wave chow chow to your shed, canopy, tent, sleeping bag or what not to "protect" your generator.
As I side note, I guess you didn't read the link I posted above. In the precautions it states, and I repeat
"Never use a generator indoors
or in an attached garage. A portable generator is an internal combustion engine that creates Carbon Monoxide.
Be sure to place the generator
outdoors where exhaust fumes will not enter into
enclosed spaces. Only operate a generator in a
well ventilated area protected from rain.
