flyer1704,
My two main routes are:
SR23 north to 176 out of Marengo to RT14, through Crystal Lake to Barrington.
or
back-roads through Huntley, Algonquin and Barrington Hills to Barrington.
The choice depends soley on my mood, as they're equal in time and distance. The Crystal Lake route provides that 10-mile, straight-as-an-arrow stretch between Marengo and 47 for those high-speed, multiple-car passes, as well as plenty of four-lane for stoplight "opportunities". The Algonquin route has curves, hills, etc., and is more scenic.
We've probably passed a few times. Check my pics at
