How do you say hi to a cowboy?

I'm curious, how exactly would you greet a cowboy in a respectful and fitting manner? What's the appropriate phraseology or gesture that's commonly used to say "hi" to someone who embodies the rugged spirit of the American West? Could it simply be a nod of the head, a handshake, or perhaps a more unique and traditional form of greeting that's unique to cowboy culture? I'm eager to learn the ins and outs of this particular etiquette.
