This seems like a super easy target for a foreign actor to sabotage and cause massive economic setback
In fact, I could almost imagine that sabotaging this thing would actually have an economic boon as it would allow the roads to operate again (rather than shutting them down for days to move a 10mph mega fridge).
Consider, for example, the economic damage of the camp fire wildfires. That was caused by a single downed power line.
So why are they called camp fire wildfires if a camp fire was not the start of it?
