Driving home from work, I work in Arlington Heights Il. and commute to my home town of Antioch, that transition zone of 37 miles is pretty amazing, it goes from no wild acreage, to hundreds of wild acreage in about a 10 mile stretch. Amazingly most of the actual sightings north and west of Chicago have been in that transition zone, say 5 miles from the heart of suburbia. These sightings include one crossing a road at 4pm which was only a mile or so from two large nature preserves. The other was in the 70s in the same area, and just a few miles west another sighting turned up recently on the Prairie Path bike trail, and this was in daylight. All of these locations were around houses within a semi rural setting, but very close to larger expanses of denser woods. A common thread are that railways were nearby, and the greenways between all these sightings connect nicely, sometimes with not many options. The possibility of a greater north/south migration is facilitated by the Fox, Illinois, and Mississippi rivers, not to mention the Des Plaines, Kankakee, others. Numerous small streams do the area and also provide limited habitat during my hypothetical migration. Southeast Wisconsin just to my North has had some pretty famous action, including the deer stolen from the pickup truck by a bi pedal creature at about 4am. That is only 10 miles north of me or so. Farmland fills the gaps between forest and marsh, corn being the predominant crop, standing 7 feet tall or so in late summer. Need I say more, but I will. Deer and Coyotes are especially healthy and abundant in our area, and every variety of small mammal as well. Wolf's and Black Bear are making appearances along with the occasional cougar. Hell, this is just like when Daniel Boone ventured across the land, well not quite but you get my point, nature is really making a come back in some areas, mine being one of them....
