In your country, are there any regional accents that are so impenetrable that you can have trouble understanding what the person is saying?

I’m not really referring to dialects, just accents that someone speaking the same language you speak might have.

There are a fair number of regional accents in the U.S. and even the “Southern accent” varies according to what part of the south you are from; there’s a variety of regional accents in the northeast, etc. but…

you really don’t ever have trouble understanding people. Except once, for me. I met this guy whose East Texas accent was so heavy that I basically couldn’t understand him, even though he was speaking English. He was a friend of my friend’s husband and they were all laughing a going back and forth and all I could to was stand there and smile and nod my head occasionally because I only understood about every fifth word he said
