Thats crazy as fuck...
I member those things, when i was a young one i had a tree fort and we would find those nests of them things (we called them army worms) and we would put blackcat firecrackers in them and blow them up.
BUT the nests never got that size and never coverd my dammed bike..Sick, personaly i would say fuck it and leave my bike there and buy a new one....
i hate bugs
