Thanks for the info, T-Bird. That could be right. Although Okfuskee seems a long way away, I know that plume really spreads from a large wildfire.
Somebody else was saying they were traveling on I-40 and saw a horizon-to-horizon smoke plume the other day. I was traveling up highway 75 near I-40 2 days after Christmas and saw the same thing (I suppose). It was unbelievable. The sun was just a red ball behind this massive gray cloud, and it went almost to the eastern horizon.
That was Bristow. It had another one today.
