Pete ... I didn't think it was ... but it could have been a controlled burn that got out of control.
A day later, I still haven't heard what caused the fire.
As I know you know (so I'm saying this for the benefit of others), while hundreds and hundreds of acres were burned ... much of it was natural prairie ground ... and in the end, fire can be a good thing, because it's nature's way of recycling back to natural prairie.
In days of old (which Morgan and George probably remember), lighting
would touch off large prairie fires, which would regenerate the prairie.
So, as long as the campground at Illinois Beach State Beach survived, I guess it's a good thing.
