Drove up to Boston Logan yesterday, half back roads, half highway. Low 40s temps, wet roads, some rain. Was at about 70 mpg before the highway, think I would've been up near 75 or more if there weren't so many stoplights on the route I took (even at 5:30 in the morning!). It got down to around 64-65 after going faster for awhile, then stop and go traffic brought it back up for the end.
67.3 mpg over 67 miles - one gallon to Boston!
