Maybe it is just the luck of the draw or familiarity of the route, but once I get to the 24 (which takes me 20 minutes on mostly dirt roads, I really do live in a remote spot!!)
I do 110 practically all the way. I could go faster if I didn't worry about getting stopped (also luck of the draw it seems).
But as I said, bottom line I might save 30 mins - an hour going your way once I know the route, but at the moment that is not important to me. I enjoy the time in the car with the kids, we sing we play games etc. It is part of going to work (or coming home). While they still enjoy it, I need to make the most of it.
