A few authors I really enjoy that write about Colorado are Kent Haruf and Sandra Dallas. They are both such great writers.
I have to say my favorite book I have read about MT is certainly A River Runs Through It. Love that book. Do you have other MT recommendations?
I have Missola on my shelf and I read a long time ago on a trip to Glacier Park Night of the Grizzlies. Kind of a scary one to read when your camping. 🙂
