The bike path on a weekend? Surely you must be joking!
I'm not joking. And don't call me Shirley.
Seriously, if you can make it up to Evanston, the ride that I like is to park your vehicle at NU by the beach at the huge public parking lot there and ride Sheridan north as far as you like. We've ridden to Waukegan and back, turning around at the second hooker.
Benefits to this ride are:
Merle's in Evanston for lunch: big bell jars of beer and good bbq.
The roads are pretty good.
This section of road receives a lot of bike traffic and the cagers are wary of cyclists.
Enjoy!
