After a bad snow storm, how many days (or hours) does it take for you to go crazy stuck in the house?

We had a terrible storm in early May. It took out the power and the telephone service. Town was 5 mils away but the roads were completely impassible. We lived on a farm so we had livestock to look after. After about 4 days I skied to town. The storm was over but the power lines were down all over the place. I remember the farmers fixing their telephone lines using horses and rafts in water too deep for a tractor.
