RE: South East Oklahoma
The terrain there is not only steep, it's pretty rocky. Large conifer trees all over the place. Rains a lot, too.
Though the elevations don't get much above 2,000 feet, even when it's sunny in the valleys it can be completely fog-bound up on top.A cruise along the Talimena Skyline Drive, which is beautiful on a sunny day, can be a hair-raising experience when you can only see ten feet in front of your car.
