100MPG at 50MPH target speed

I've recently arrived in Vermont and now that it's warming up, I've had some seriously good trips - better than I would have imagined this time last year. The gently rolling hills, low speed limits, and relatively long distance to anything are practically ideal for eco-driving. I have aspirations for more, but for the first time I can honestly say I'm very, very happy with what I'm getting. My biggest complaint right now is that it takes so long to finish a tank and put it in my log.

Local drivers like to greatly exceed the speed limit (which is usually 50), and I feel bad about collecting a line of cars behind me by driving well below the limit. On a warm day after the car is warmed up, I've found that without EoC I'm getting about 85mpg, and with moderate EoC I can sometimes creep up to nearly 110mpg if I let my average speed drop just a bit below my target of 50. Generally I'm cruising between 48 and 50mph in lean burn, with EoC downhills, and arriving home from the longer trips with an average of around 95mpg depending on the weather. There have been as many cold and/or rainy days as not.
