I'm again cleaning animal nest debris out of the cozy home they make in the valley under the intake. In the previous events, I knew what the nest material was and where it came from. In this case, I'm stumped and concerned. There is nothing in my garage like the material I found and I wonder if they might be tearing into something in the LC. For those of you that have poked around in odd places, is there any insulation or padding in the LC that's white? There was a LOT of this in the valley; it clogged the 2" shop vac hose.
