There is even a website dedicated to the preservation of "America's Cowboy heritage". So far only a few states have passed resolutions on making today official; Texas only passed it this past March.
From the website, which took this from James P. Owen's book, Cowboy Ethics: What Wall Street Can Learn from the Code of the West:
Code of the West
1. Live each day with courage.
2. Take pride in your work.
3. Always finish what you start.
4. Do what has to be done.
5. Be tough, but fair.
6. When you make a promise, keep it.
7. Ride for the brand.
8. Talk less and say more.
9. Remember that some things aren't for sale.
10.Know where to draw the line.
Well, obviously this is a topic that requires a lot more time and care than I am able to give it today, so check out the websites I've made links to in this post, pop a John Wayne movie in the DVD player, and give your nearest cowboy a hug.
