I don't have it: fear of their presence or existence, but I sure understand it. I have friends that are petrified of snakes in any location, ie stores, a handler's hands, the zoo.. and who modify their outdoor behavior to avoid where they think snakes are. I have one who wouldn't even drive to a mountain resort "because there are snakes there".
Well, yes, but they're not roaming the streets eating people. At least, not that often.
I suggest, if you want to be outdoors, learn up, expose yourself to them and adopt some behaviors such as walking stick/trekking poles and enclosed tents so that you can walk and sleep in some greater peace.
In SoCal, there are plenty of rattlers, depending on season and weather, and those are the one to be bothered by. We've got plenty of non-poisonous snakes that are cool to see and won't savagely drop down onto your neck from overhanging sagebrush like the dreaded Western Furry Rattlesnake I like to tell my Scouts about, and there are plenty of rattlers you may see on trail. If they're on trail and gentle, distant suggestions will usually result in them leaving. However, if you or others need to pass by and the snake doesn't move on or coils and strikes at you, then a *long* stick or tossed pebbles can often move the critter. However, tossed pebbles, tossed trail sand or even the stick can make Senor Snake mighty angry, so be smart and then take the time to get him "really" off-trail, not just into the weeds...
On a trail called Sycamore Cyn, near Malibu, we crossed 14 rattlesnake snakes in trail one morning, over 3.5 miles.
I used to drive up and down a steep access road north of Los Angeles (Browns Cyn) and would see, literally, dozens of rattlers on the asphalt every day. They'd be aggressive and would occasionally strike at the car or truck -- you'd hear the thunk as they hit the rocker panel. Once, one got stuck in the sidewall of my bias-ply tire for a revolution! I have to admit, we went out of our way to run the bastards over most of the time, as we also had to hike that road. Hat bands and appetizers.
Let the bunnies live. They're cute.
