How often does natural gas go out (during natural disasters or otherwise?)

I got a firman generator

Its pretty great because it runs on natural gas, propane, and fuel. I tried it out over the past few days and its doing great.

I have not bought a large gas can (13 gallons or so) because I am betting on relying on natural gas for the most part in hurricanes/freezes/and zombie apocalypses.

How often does natural gas go out around here?
