When you swim and/or play around a river in Illinois, you know you need to expect the unexpected. But, in this case I would guess that what was really found is something few would never expect. Yes, a 12-foot bull shark really was found in an Illinois river and there are video and pics to prove it.
When that gas gage reads empty on your car, you might get into a panic on how far you can go until you run out of guess. Hopefully, this piece of information helps.
