Luke, keep in mind a few things about rattlers: number one, if you hear them rattling they are aware of you, and are simply asking you to leave them alone, and to note their presence. It is not a threat, it's an alert. Though they probably have different intensity of rattling which someone more clued in than me could probably understand in terms of fear and warning levels.
This would be one of the top reasons no hiker should ever hike with music player attached to their ears, you just lost the friendly warning seconds and might step right on the little guy, even though he really wanted to tell you not to do that. So if anyone ever gets bit by a rattler while using their mp3 player, blame yourself, not the snake, in nature creatures don't ignore their environment and tune it out with fake sounds.
I did talk to someone last year who noted that she'd seen some rattlers on the overgrown trails she'd been bushwhacking on up high in Big Sur, under the chaparral, but on the trail. So it pays to pay attention at all times.
One way to get to like snakes is to stop when you see a garter snake, they are small, friendly, and shy, and certainly aren't going to try biting you, and even if they did, it would probably just be sort of funny. Just watch them move, watch how their bodies create the motion, watch how elegant their forms are, how they can vanish into the underbrush. Those snakes are out now on the trails, I'm seeing them all the time hiking, and they are a great one to get used to the notion of a snake in the wild.
Also, as a mental exercise, and this is easy to do in Big Sur/Ventana, try to remember that the lizards you see doing their little pushups when you pass by them looking cool are the cousins of the snakes, well, maybe second cousins. Snakes just don't have the little legs, at least not visibly. Same for the salamanders and newts you might run across.
There's some good tips in this thread, using trekking poles is I think probably going to alert the snake you are coming, that sharp sort of tap is probably enough to either shake the ground or to let them hear you. I'd only move a snake out of the way if it was sunning itself right on the trail, and then only after asking it to move, which they will almost always do, they don't really want to deal with you either, shocking as that might be to our egos... But they might take a minute or two to decide to leave that prime sunning spot that they had discovered. Like Roger said, take some pictures, or just watch it, see how it moves and reacts, might learn something. Maybe if it's stubborn carefully suggest to it that it really needs to move, by moving the trekking pole tip closer to it.
Very cool shots of snake handling, but of course, most people shouldn't try that, but nice to see snakes get some love here, all the creatures should.
