Yessir, supposedly they really don't know for sure, and the game changed through the years, so the "documented" history of the "modern" game is what I posted. If ya' want to go WAAAY back, some of it is just guessing.
From the net: Some say it was invented in 14th century Germany. Others credit the Blackhawk tribe of Illinois. Still others point to a Kentucky farmer in the 1800s.
(I'd still rather pin it on those corn-holin' Yankees.)
I'd lean toward the Midwest since the bags are filled with corn. If'n it'd been in the South, they would'a been beanbags and we'd be beanholin'!!
