Yeah... my power is back on. 70% of the town was out, including the main road through town where all the stores were. The main road was back on Wednesday morning. Predictably, every last store in the blackout area of this town (and a neighboring town I go through to get to work that also had major power loss) was closed. There was one exception, a Hess station, that was very busy; they must have had a generator. None of the other gas stations in the area were open. Not actually needing any gas, I didn't stop in to figure out if they happened to have working credit card processing, or if it was cash only; I should have stopped in just to find out, although it was very busy so I didn't. I'm guessing they wouldn't have been able to process CC's.
If a Mom and Pop shop could have stayed open to sell coffee, they would have made a lot of money. Everyone driving around looked like they were desperate to find some place that sells coffee. After all, how many people these days can make their own coffee at home without electricity? (I used a percolator on a Volcano stove.)
One thought I have is... if the grocery stores were closed because they had no power, then what about power needed to keep their food from spoiling? I think I'm going to avoid buying any perishable foods for a while just in case they are reselling any of it.
