Come to Idaho.  Be no problem finding a nest of rattlers out on the desert.  

We used to have garter snakes hanging around when I was a kid in Idaho too.  I used to love those little guys because they helped keep down the mice population.  I honestly haven't seen one in years though.  

I am not a fan of snakes, but spiders freaking CREEP me out. I know logically they are cool, they keep insect populations down, and the varieties that can harm humans are a miniscule proportion of total spiders. I know this in my mind.

But still.

Illinois has mostly non-venomous, though Timber Rattlers can be found in deep southern Illinois, as well as water moccasins. Mostly, we have garter snakes and king snakes, maybe a black racer. Where I grew up, there were fields around the outskirts of town (and we lived at the edge, with a farm on the other side of a fence) and you'd get snakes both inside the town and coming out of the fields, when planting or harvesting disturbed them.

I had a couple of encounters, as a kid, that always stood out in memory. The first was when I was in the first grade. We were outside for our organized recess (not quite PE, but teacher-led) playing some game and a snake (probably a black racer, based on the speed) just raced along the grounds, towards a field. Everyone started screaming and jumping away from the path and that sucker booked on down to the field. Scared the crtap out of me to see one moving that fast. Even on tv they moved slowly and menacingly.

The second encounter was later. I grew up in Central Illinois, near Decatur. About an hour to the southeast was a town called Shelbyville (and, yes, Springfield is our capital, but it is further away from Shelbyville than Decatur is). Way back, the US Army Corps of Engineers damned up the Kaskaskia River and created a system of artificial lakes, which was used for campgrounds and fishing and pleasure boating. We used to go camping there, with my maternal grandfather, who liked to fish there. We'd keep our boat anchored on the bank and camp up at the top of the hill, at a section called Wolf Creek (There was Lithia Springs, the first one and most developed, Wolf Creek, Eagle Creek and Coon Creek). We tent camped, but my grandparents stayed in a camper. There were trails through the campgrounds and ones that led down to the banks of the lake. Sometimes we left our catch in a basket, in the water, waiting until the next day's fishing, before cleaning them all. We went down to the boat, after breakfast, to head out and my dad pulled the basket out of the water. There, trapped partially inside, was a water snake, that had swallowed a fish and couldn't get out of the basket mesh. I jumped out of the boat and ran screaming up the hill and wouldn't come near the boat until my father had cut the head off the snake and threw the carcass far away from the boat. I was edgy all day, watching for water snakes (and you did occasionally see them).

Spiders don't bug me, but snakes do. My brother, though, is afraid of spiders. Thing is, we had all kinds of daddy-long-leg spiders in our basement, throughout childhood and he never showed a fear of them; but, he says that was why he doesn't like them. I used to just casually smoosh them. Snakes aren't as easy to smoosh. However, I have deliberately mowed them. I've seen The Six Million Dollar Man. They will try to slither up on you and attack!

I saw some Quora posts once from snake ‘owners’ who seemed to have thought they’d ‘domesticated’ them.

I’m no snake expert, but I’m gonna presume you don’t even semi-domesticate them. I expect that at best they’d tolerate you and get used to your presence. There was a documentary once where a seasoned python owner had to call for help as the snake had constricted her arm during feeding time. Seems they are unpredictable.

A guy on The Chase, while being asked about hobbies, said he was a snake owner and was looking for permission to keep an anaconda (UK). Sounds like a death wish to me. If a seasoned snake owner can struggle with a boa, I shudder to think what a person would do if an anaconda went rogue. I had to pick up my sister’s unruly cat (gently) and place it in her garden while I was looking after it when she was on holiday. Simple. Doubt I could pick up an anaconda, tell it off and place it somewhere.

There was even some guy who claimed he’d domesticated a cobra that would gently lick him. He probably was joking and not expecting to be taken seriously.

I did Google some stuff about this once. Seems to be a lot of stuff to get right while keeping snakes, from making sure your hands are free of the odour of any dead rodents you’ve handled to making sure your body movements don’t antagonise the snake. Doesn’t sound like a pet to me!
