More info: I'm in northwestern Illinois. The driveway is level. I'd estimate the straight part is about 100' long, but then there's a semi-circular driveway that's probably 150-200' total.
I have a Consumer Reports digest that says there was a snowblower report in Oct. 2004, which was right before we subscribed.
If anyone has that info and wants just post the bottom line, that would be great.
