Believe it or not, I remember hearing of celebrations of Juneteenth when I lived back near downtown Buffalo... somewhere near 1985-6. There was never anything saying what it was about, just that it was Juneteenth, and blacks (African Americans) were the ones celebrating it. No offense intended, but I thought it was a bonus welfare check holiday at the time. Remember, this was downtown Buffalo in the mid-'80's, and I was riding the bus down Broadway watching school children eating salt & vinegar potato chips with Orange Crush or grape soda for breakfast.
