This is completely asinine, and almost trivial, but...
I just found out, if I go to a fast food place with the car cold, ~1.7 miles away. I only get ~4.7mpg...
I love my bikes!

Interesting - I know cars get crappy mileage until they warm up, and short trips (1.7 miles like you said) are horrible for mileage too. Yet, the majority of trips are these short hops.
