Squirrels chewing on lines???
That one eating meth and going crazy was so recent. Maybe that woman with the signs "You should bought the squirrel clothes" in the movie set them off.
However, they are saying "a fire in a power substation." Cover story or maybe even accidentally the truth. We should still but the clothes just in case. Can't hurt.
Sqirrels do not chew on lines. There are exposed wires tapping transformers. Squirrels make contact with that exposed connection and short out the transformer, dieing in the process. Birds, especiallly those eating fish produce the same result.
The remedy is very simple. A plastic insulating cap placed over the connection prevents contact
