[Healeys] Speeds, distances, and odometers.

[John Sims]

Personal aside:

Aren't we getting a little technical and/or anal about MPG and speed.

There are countless permutations involved here guys. 

Tranny ratios
Gear Box selections
Tire sizes, 
Fuels used
Additives to the gas
Gear Box Lubes
Tranny oil
Leering at the passenger and slowing down as the eye signals become stronger
(opposite sex, I hope unless it has been a very, very, very long trip)
Freeway versus two lane highway 
Number of stop lights
One horse or two horse towns gone through with artificially low speed zones
(AKA speed traps or revenue enhancers for the town)
Altitude
How recent was the build of the tranny, OD, Speedo, odometer, at idle while
looking at a deer on the road, yadda, yadda, yadda

Ad nauseum which is a better way of saying yadda, yadda, yadda

I loved reading the "blogs" that  everyone was kind enough to share on the
list but . . . . . . . . . . . . . .. . . . . .
