I love postcards featuring an entire state. The shape of Montana lends itself well to this, as noted in a previous post showing a card actually shaped like the state.
Montana claims a piece of my attention sometimes, in a variety of disparate ways.
1. Ivan Doig. He's been called the "dean of western literature" and a "worthy successor to Wallace Stegner." If you haven't read his novels, particularly the "McCaskill trilogy", consisting of English Creek, Dancing at the Rascal Fair, and Ride with Me, Mariah Montana, you've missed out on something great, especially is you have any interest in the history of the American West.
2. My friends Claire & Steve. They moved to Montana last summer. Steve attended college there and Claire is going back to school for a MSW (Masters in Social Work, specializing in hospice care) after 30 years in the travel business. Yeah, Claire!
3. Big Sky. My friends John and Cindy have a recently completed building a compound. We spent time at Big Sky when the compound was just a glimmer in John's eye, and haven't yet seen the finished product. I imagine it to be pretty wonderful. The whole area is beautiful and close to Yellowstone and offers a wide variety of winter and summer sports. However, the day we left it was 30 below zero at the Bozeman Airport. Brrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr.
