Well, I'm in Oklahoma and fortunately I didn't lose power. But as to how long it will take. The last 2 ice storms (Christmas 2000 and January 2007) at McAlester here in Oklahoma my brother-in-laws house was without power for 11 days. But it depends on a lot of factors. Out in the country there were people without power for up to a month. Some places they couldn't get trucks in and had to carry everything in.
