It's super awkward but I can get to it from inside the house (between insulation and hole). Going to have to move my workbench but so be it.
Any direction on the type/brand of foam I should use? I have a can of fireblock to seal ethernet runs from my basement to main floor, though it's probably seized up by now.
Might be onto something, I've been finding delicious brisket sandwiches outside my house. Even found a knish the other day.
