Unbelievable! That is so beautiful, and the peeling paint and the screw in the corner provide such an interesting context. I'm so glad you stopped, and took this picture.
Our family so much enjoys your pictures and we visit often. Thank you. Hope you don't mind our identifying your moth. It is the Cecropia silkmoth (Hyalophora cecropia). Moths of Montana http://www.npwrc.usgs.gov/resource/distr/lepid/moths/mt/998.htm
Good luck with your branding!
