Where do black snakes hibernate during winter?

since snakes are indigionous to the U.S. the tend to go, in the fall so they can make right up to Bubuts penie. yes in the winter time they start their jouney to Bubutts penie so they can enter it and stay warm for the winter. eventually Bubutts penie gets too crowded and some decide to go in his but. so in fact there isn't a stick up his but, there is a bunch of ravenous snakes in it.
