Illinois is the
Fifth and best Sufjan Stevens album. "Land of Lincoln." (Try to top that, Indiana!) The preceding is a standard case of liberal deceit, as everyone knows Lincoln was born in Kentucky. Its other nickname is the Prairie State, which tends to be used less. It got its name because the roads there are so rough that they make you ill and annoyed.
Peoria is in Illinois, and it always matters how things will play there. The uniquely named Oblong is also in Illinois and calls itself "The Only Oblong. If a citizen were to marry someone from Normal, Illinois, the announcement would read "OBLONG MAN MARRIES NORMAL WOMAN." Illinois is also home to the city of Chicago, known as "the city of broad shoulders" and "America's hog butcher."
Despite the dominance of Chicago, Illinois is a leading agricultural state. It ranks second only to Iowa in the size of its corn and soybean crops though surpassing them in production of dirty politicians.
If you happen to be in Springfield, go get a horseshoe, they're pretty good.
Chicago's corruption is like our pizza
Every city has it, but none of them do it quite like we do! (And ours is deeper than everyone else's!)
Twelve Chicago Democrats walking through a cemetery taking down names is a "get out the vote" rally. And yes, Chicago pretty much is Illinois, the way Chicago votes determines the governor, senators, and electoral votes.
A point of much embarrassment for many residents is the tendency for Illinois Governors to be crooks or try to sell Senate seats (we're looking at you Rod). But none of that matters, since the state has been unilaterally ruled by the one-man Michael Madigan Party since 1983.
Illinois holds the dubious distinction as the state where two followers of Lyndon LaRouche won major contested elections, in the Democratic primaries in 1986 for Secretary of State and Lieutenant Governor. These primary victories are widely regarded as a fluke resulting from downstate Illinoisans voting against the Chicago machine candidates, as they usually do, without knowing anything about LaRouche. This sent the state party into panic where the party-endorsed candidates ran on the Solidarity Party ticket and the LaRouche followers on the Democratic Party ticket, throwing the election to the Republicans.
Fun fact: Illinois residents have the lowest amount of trust in government out of all the states.
The plural of Illinoisan is Illini.
Tackling Illinois's highest point
If taking on the big mountains of Nepal and Tajikistan is too much for you, you could instead tackle Illinois instead. Even the obese of Illinoisans (oh sorry Illini) will be able to tackle the beast that is Illinois highest point: Charles Mound. Sticking out like a (not) sore thumb out of the flat plains of the Midwest, Charles Mound is only 376 meters in elevation. To get the idea on how low that is, the Sears Towers in the Windy City is higher than Charles Mound! 
When you visit make sure you take a good view of the rest of Illinois because it is the best place in Illinois. It only goes downhill from there.
