The animal encounter poem is now so distinct a genre that it would be possible to create a full-length anthology from deer encounter poems alone, and many varieties of experience would emerge from such an exercise.
With fiction, I tend to get to my desk and start writing. Poetry I write in my head, often while walking, so that my poems have an organic quality, hopefully.
My poems tend to be more celebratory and lyrical, and the novels so far pretty dark. Poetry doesn't seem to me to be an appropriate tool for exploring that.
