David, I have perhaps an unusual suggestion for you. I've had a hankering for a story (maybe fanfic wouldn't be the right word; perhaps more like a backstory) that employed the fictional Brokeback Mountain from a Native American perspective. I think it could be so fascinating to read a tale depicting that setting before those of European descent settled the West, and to show the mountain's numinous power in full force long before Ennis and Jack even entered the picture. I have a belief that the lives of all that have gone before us cast their shadows over our present activities, and I wonder about what other human stories ole Brokeback harbored that may have tinged the story between the two boys we have come to know so well.
Given your expertise in your Native American heritage and your wonderful storytelling skills, I think you would be a natural for such a work, if you had any inclination to pursue it. Just an idea to throw out there. Also, if you didn't feel like undertaking this kind of project, would anyone know a Native American-inflected story with Brokeback as a setting (whether past or present)?
