Haha, this just reminds me of archaic english. I haven't read all of this, but I'm surprised the people writing with their big, long words and short, hard words don't seem to have mentioned that "on the morrow" is a very, very old phrase.

Perhaps it is the rest of the country that phased out the use of the phrase, and not the other way around? Northeast Georgia is actually one of the places in the US where the language has changed the least over the past few hundred years.
