How Can I block all IP's from a certain state or even city?

I know it may be weird but I was curious. Let's say if I want to block all californian's from seeing my site how can I do that. Also maybe even just people in Las Angeles. Is that even possible? If so how can I do that in my .htaccess.

 

Is this even possible?

I don't want to pay for anything. There should be something am I right?

Deny, State "California"

I don't know something like that lol.

 

If you pay peanuts, you get monkeys
