miles per dollar

Like most, some, a few, ok, maybe it's just me -- nerds, I keep track of most of the relevant numbers in my life. Perhaps a little obsessively.

(The gap is when I either didn't have a car or kept lax statistics.)

I'm getting only 1/7th the miles I once did, per dollar of gasoline.
