This is a list of much used gear during my week with no power in NYC.
G19 (Glock 19 9mm pistol. DM)
870 with SF light (Remington 870 shotgun with SureFire weapon light. DM)
4 Bassett hounds
MREs (Meals, Ready to Eat. DM)
Bottled water and stored water in jugs.
Oil radiator heater
Having this stuff prior to the storm made my life a hell of alot easier. So if you don't have any of this, get it.
