I have the same issue almost... Snow here in the Western Carolina Mountains today! But, this area is not a metropolis like you deal with, it is a rural area with mountain roads - curving and winding, it takes me 30 minuets to travel 15 miles. Good thing I enjoy the scenery, although it gets a little frustrating time to time when I'm traveling on a two lane (which is the majority of the time) and get behind someone going under the speed limit. I just have to remind myself that I'm likely behind a future customer and back off!
