be advised propane or any heater including a gas stove will put out carbon monoxide. this kills u in your sleep. also b4 u bet on the gas stove n matches, try unplugging or trip the braker n light the stove NOW!!! the new stoves have safety relays that lock out the gas/hence wont work. if power is out city-wide will t affect the gas coming to your town n house? if u r talking being out for days not hours the gas will get used up that is already in the pipes.
if u r talking days ,try sleeping at hospitals. they do have gennys. longer thou u is looking to move out of the city.
