The one huge downhill I have in the morning, 1/2 mile long, 25 mph speed limit. I usually hit 40-42 mph. I take the lane since I'm going faster than the speed limit. Great cool wind at 7:30 AM, even during the hottest summer days it's still nice and cool in the morning.
Unfortunately there is a 1-lane underpass at the almost-bottom of the hill so I don't get to do much with the accumulated speed.
Oh yeah, and I don't have to go up that hill at the end of the day, either. That would not be fun.
