On my drive around the lake today I noticed, in many places, that the highway was paved with caterpillar guts. Aspen trees for miles on end were stripped bare of their leaves. Parts of the highway are dark and look as if the lanes have just been oiled. Millions of caterpillars lay dead on the highway. Possibly billions are chomping trees in the bush. Looks like it's a major Tent Caterpillar invasion.
