Now that I'm in Vermont, gas mileage has skyrocketed. 35-50mph rural roads with gentle hills are nearly ideal for hypermiling, and this first tank is looking to be around 80mpg despite cool weather. I've been close to setting my 220% EPA trip record.
The dirt road leading up to the house is generally what kills it though. My best trip (with zero elevation change) was 109.9mpg by the car's readout. Perhaps once I reinstall my grille block, I can make it.
