The rest area itself isn't much to speak of- located in a dull stretch between Galesberg and Peoria, Illinois. It is secluded enough that it has a bit of a creepy 'rest area' vibe to it, actually.
I like the thought of it though as I enjoyed reading Edgar Lee Masters's "Spoon River Anthology". There is a lookout which otherwise is kind of random, but allows you to look over the area, and I think of Masters when I do this.
New Englanders settled here and it is an area rich with early American and French settlers and Native American history. There is a feeling that I think is distinct from Southern Illinois, and that feeling is largely autumnal.
Anthology was published in 1915 and is a series of poems attributed to the dead citizens of the cemetery. Masters wanted to "demystify rural and small town American life." 212 characters tell their tales, some with secrets, observations, histories, and fragments; occasionally with the revelation of a good country song.
Of course, this led to some controversy in the town of Lewistown where Masters was raised. Sort of a "You're so Vain" of its day. it was banned in Lewistown for 60 years, up until 1974. Master's mother was on the school board and voted for the ban. Local historian Kelvin Sampson notes that "Every family in Lewistown probably had a sheet of paper or a notebook hidden away with their copy of the Anthology, saying who was who in town.
In recent years, the town has started to embrace the legacy. While reading about this, I ran across a Masters-themed tour of the Oak Hill Cemetery. There are 40 markers that represent characters who show up in Anthology. The cemetery also is nearby an area where Lincoln and Douglas debated and the courthouse they spoke at has burned down, but the pillars they stood on remain.
