On the freeway, I tend to get into the left-hand lane, and ride on the left side of the lane, unless there's little berm, then I go to the right side of the right lane. I tend to exceed the speed limit a bit though, even on the too fiddy, as long as the traffic isn't backing up in front of me. I prefer to get out in front, into the "clean" air, since especially the 250 is thrown around pretty easily in the wind.
