you had best be prepped. at the very least go to aldi's buy beans, rice, corned beef hash and a few multivitamins. hit up goodwill and buy 0.99 bug round candles, and get some matches and reading material. +an AM FM radio, pref a good ham unit. you should already have plans for water, asswiping, first aid, and plenty of guns and ammo.
Good Luck.
