Is it the grid and the possibility of another great blackout (due to a lack of breakers)?

Is it the unpredictable terrorist act that could blow up a pipeline in North America (which includes friendly Canada)?

No, it’s Sciurus Carolinensis!

Maybe Dark Verne has the right idea when he thinks we need to Get Rid of that Squirrel!.
