I've always thought of cold all the time, like with snow hats and men drinking vodka and strong women. I guess testy tempers also? A very strong military.
But then again, I'm from Texas and I'm not a cowgirl, I couldn't ride a horse to save my life, and the only accent I have is using the word, "ya'll". And there's no tumbleweeds. lol. So stereotypes are frequently very incorrect.
