I find it hard to image that there was not at least a single lighter in the group. While this is national forest, it is NOT wilderness. It is crisscrossed by county roads, fire roads, and hiking trails. This the Ozarks, not the Rockies, but the hiking can be tough.
I wonder if these guys will actually go to the trouble of making a PSK, then stowing it under the seat of their bikes. Nothing fancy, a trash bag, some matches and tinder in a watertight container can make a miserable night much more tolerable.
This is the same campground hit by a flash flood in October, during a 4x4 rockcrawling event: 200 were stranded, 28 had to be rescued, and 3 rescue personnel in a boat capsized and had to self rescue.

Here's video of a flash flood on a tributary to the river. It goes from clear water to flood in under 1 minute.
