Absolutely avoid traveling to the US if you don't have to, but New York and New Orleans aren't total dumps as portrayed by these cherry picked images. I'll also point out that residents of both those cities overwhelmingly oppose Trump and vote heavily Democratic. And New Prague? Never heard of it!
New Prague is a small town of about 9,000 people in Minnesota. I’ve never been to New York or New Orleans but I love Minnesota and would welcome and encourage anybody who’s interested to visit.
