I'm inclined to agree.However,two things make me wonder 1) at this time of year you get full daylight at 0600 2) although I don't know Chicago well I think I've read that Wilmett is a fairly prosperous,if not *very* prosperous,suburb.If I'm correct about Wilmett it would seem to lessen the chances of foul play.
Wilmette is a little further from Chicago than where I live in relation to Detroit.
The suburbs surrounding Detroit are prime hunting ground for home invasions and auto thefts committed by the ferals driving out from the city.
I hope she is safe but her case is similar to that of a teenage girl who was found on a popular bike trail north of me several years ago, beaten to death and raped. Her killer was caught and he was a young white kid that lived in her community........
As a poster mentioned above, wooded bike trails for lone women either running or biking or in-line skating are recipes for disaster. They have to be very careful of their surroundings and DEFINITELY SHOULD NOT be wearing those earbuds and listening to music.........
