According to the information out there, the eclipse looks like it will begin in this area at 11:50 am, reaching it’s peak around 1:18 pm and ending for our area at 2:45 pm. As we know, we are not 100% eclipse here. But, according to various maps, we’ll be at 98% magnitude and 98% obscuration for the event. Meanwhile, there are expected be better than a quarter of a million visitors to deep Southern Illinois to see the eclipse. But, there are many areas in Missouri, Western Kentucky and such, that would be a fairly short drive from here and might give you a less crowded situation to see the event.
