"I used about 123 gallons of gas and less than a quart of oil, on the
trip, and when I landed I bad enough fuel for about four more hours."

$30.91 for 123 Gallons seemed a little inexpensive until I found this:

"Source: New York Times Dec 2, 1938 "

Ah! Late breaking news. ;-)

That comes out to ~$0.25/gallon. Assuming avgas at ~$5/gal in 2008, then
over the 70 year period that translates into average inflation rate of
about 4.37%/year.
