Great questions, Stray Cat. The "guy" you are referring to is actually a woman and that is part of the reason I ended up going to the Oasis in the first place. What you don't see in the photo are her intestines dragging along behind her, the anguished look on her face as she clutches her midsection in a feeble attempt to slow the evisceration.
You see, as I approached the Oasis, coming from the east on I-90 (you were correct J_B) I noticed the woman trying to jiggle her way across the ramp and.....blam!.... a guy in a light tan Pathfinder nailed her and set her flying into a metal sign. The sign's metal pole, which ironically read "CAUTION" had a large bolt protruding dangerously to the side and caught her midsection and ripped it open, causing the aforementioned guts to begin to spill. She scampered up the ramp toward the Oasis. I chose to exit at the point and follow her. I took the picture as she approached the door...
Once inside she stumbled into the bathroom and emerged several minutes later with what appeared to be several miles of toilet paper wrapped around her prodigious body. She now looked like the Michelen Man, with blood specked toilet paper and still visible signs of entrail oozing between the cracks.
She waddled over to the Chinese food stand (sorry, I forget the name) and ordered about three dozen egg rolls. Then she went to one of the tables overlooking the freeway and begin to eat with an intensity I have not seen for quite some time.
It was at that point that I grabbed my coffee and sat down at a nearby table. From my vantage point I could watch the big trucks rumble by below, while at the same time keeping an eye on the fat woman eating the eggrolls.
Chicago is my kind of town.
