Let me preface my comment by identifying myself as an informed investigator who has been living adjacent to Cole Hollow Woods since 1993 and hikes these woods on a regular basis (most recently this past Sunday).
When the Interstate 474 bypass was constructed in the late 1970s, Cole Hollow Woods became isolated. For the past decade or so, these woods have become a playground for adults riding ATVs. These woods are no longer the same remote and inaccessible habitat area that it was back in 1972 when a creature was being sighted here.
HOWEVER, creatures matching the description of Sasquatch or Bigfoot (whatever name you choose) continue to be encountered elsewhere in Illinois.
A quick chronology of sightings during the most recent year:
October 2006 - Madison County couple report a series of sightings since June in the fields around their rural home.
October 2006 - Livingston County truck driver reports seeing a tall creature running on two legs crossing I-55 at night near mile marker 218 (near Dwight).
July 2006 - Williamson County man reports sighting at Lake of Egypt near the Shawnee National Forest (see http://www.bfro.net/GDB/show_report.asp?id=15393).
June 2006 - Kendall County couple report a howling creature that damages their fence in rural Yorkville (http://www.bfro.net/GDB/show_report.asp?id=15019).
November 2005 - LaSalle County workers up on 300 foot cell phone tower report daylight sighting of tall creature crossing road in wooded rural area south of I-80
November 2005 - Saline County deer hunter has pre-dawn encounter en route to his deer stand (http://www.bfro.net/GDB/show_report.asp?id=13070).

NOTE: Only first hand reports directly submitted by the witness are investigated and documented.
Get back to me when one is captured.
