For some reason Chicago became a prime spot to go to the US when we were freed from the Ottomans.
You don't notice them because, believe it or not, we integrate like noone else. I know second generation Bulgarians in Chicago who have NOTHING Bulgarian in them.
Veliko Turnovo was reported as 20% British recently. They're all happy as shit because they get mad farming advice from the grandmas, they get help and all. And the locals love them because it reinvigorates villages we left behind.
Also to further convince you, I have wild raspberries, strawberries, two cherry trees, a walnut and plums growing in my yard that I had left behind for 3 years. Just fucking because.
Stay away from Montana. Yes, a full meal with dessert and three beers costs about 1 quid there, but you DO NOT want to go to Montana.
Rhodopes are harder, but they are the most beautiful and magical place in the world. Go there once before you decide, because you're going to be at the mercy of nature a lot (roads clsoed for weeks due to snow, no airport nearby). Keep in mind, there's a lot of pros with the cons - like how Rhodope people are the most wonderful ever, women are the best, etc.
Turnovo is a safe and good choice.
We're perfect for an escape from the west, mild but good weather, all 4 seasons, ground is more fertile than fucking anywhere else in the world, more diversity in nature than, again, literally anywhere. We're cheaper than anywhere else (including Greece, by the way), our language is not impossible and even then, the amount of diaspora in Turnovo is enough to make it half-english speaking. Many more reasons.
