It isn't just Oklahoma City or Tulsa. It's huge swaths of this state and at least three others thawing out from the ice storm over the weekend. People are staying warm with fires in their woodstoves, some are turning on their gas stoves (not advisable- there have been at least two carbon monoxide deaths in the state already) and kids are pulling out their sleeping bags for impromptu slumber parties at the home of their friend who has the most heat.
It's already day three and there are still close to a half million people here without their lights on. There are plans to combine multiple shelters into the Cox Center, and hopefully the response here will be faster than some of the other disasters I've covered.
