I take classes online via Korea Society in NYC and like it a lot. There are a few KSs around the country that offer group classes online. You may get more from a private tutor after you get the basics of pronunciation, sentence structure, and build vocabulary

So many ppl out and about all night. It was great. Seems like it changed around 90 or so. Cops tried to enforce a curfew in the late 80s for 18yo and under, iirc. That didn’t work out very well. Had some wild times. Not always good. Still restructuring my brain and what all I normalized from back then.
