Beaver Moon

Not sure on the ground whether
there is a full blanket of moon
or a full blanket of frost
Why the beaver is in sync
with the full moon
as the November nocturne
was played from the wind of Chopin
since centuries ago
who said beavers would not enjoy
the music of night
while they get some repair work done
before the snowy winter
hmm, maybe this will be a blizzard winter
