Read this and try to doubt me:
In episode 17 hawk describes the Black Lodge, " There is also a legend of a place called the Black Lodge, the shadow-self of the White Lodge. The legend says that every soul must pass through there on the way to perfection. There you will meet your own shadow-self. My people call it The Dweller on the Threshold…but it is said if you face the Lodge with imperfect courage, it will utterly annihilate your soul."
I would like to draw your attention to "The Dweller on the Threshold."
Next point, in episode 26 Earl describes the Black Lodge in contrast to the White Lodge (the vagina). "Once upon a time there was a land of great goodness called the White Lodge. Gentle fawns gamboled there amongst happy, laughing spirits. The sounds of innocence and joy filled the air and when it rained, it rained sweet nectar that infused one’s heart with the desire to live one’s life in truth and beauty. Generally speaking, a ghastly place, reeking of virtue’s sour smell. But I am happy to point out that our story does not end in this wretched place…for there is another place, it’s opposite. A place of almost unimaginable power, chock full of dark forces and vicious secrets….spirits there are as likely to rip the flesh from your bones than greet you with a happy “good day”…And to harvest these spirits in this hidden land…would offer up a power so vast that it’s bearer might reorder the Earth itself to his liking. Now, this place I speak of is known as the Black Lodge and I intend to find it."
Note the verbage: "rip the flesh."
Two more points:
1) When Leo ties Laura up on the night of her death she says "Leo NO!" and "Don't go there." We know this from witness testimony of Waldo the minna bird. Perhaps he was going for the butt.
2 ) And, now that you think about it, don't you think entrance to the Lodge sort of look like a butt?
What do you think?

Have a nice dinner. I'm exiting this thread. Getting out while the getting is still good.
