When I was home and working, it'd be about 15 miles, a 25 minute drive each way - lots of rural roads and stop signs.
Now that I'm in college and living on campus, my weekly mileage is about 10 miles.
Next semester I'll be off campus, and I'm hoping to find a place that'll allow me a commute time of less than 10 minutes, in part because this region gets more snow than I'd expect any permanently inhabited area to receive.
