Mechanical Muses

I have a question I hope you writers will answer for me. Do you have a mechanical muse? If so, I'd like to know about it. I have one I've been riding for -- can it be? -- almost a decade now. No, I don't think I've written any stories about motorcycling, but we don't write about our muse, we write because of our muse. To some extent.

Or am I off track here? Are the euphoria and sense of adventure my iron steed delivers not to be considered the whisperings of a muse, but rather part of the normal array of emotions we expect from life? What do you think?
