Looks kinda like a Tragopogon, but has a stronger midvein and longer leaves than I'm familiar with. (NW Indiana)
Doesn't look right for a Tragopogon, that has different leaf layout on the stems. Sorry, don't know what it is, though.
Lactuca graminifolia looks very limited in my area, but could be spreading among waste areas: http://plants.usda.gov/java/county?state_name=Illinois&statefips=17&symbol=LAGR
