In the last couple of weeks, gas around here (Iowa) has dropped 10%,
back down into the $2.70 per gallon range. (This is mogas, obviously
-- the only stuff I'll burn in my plane, if I have a choice.)

I actually paid $2.67 per gallon last night.

Wouldn't sweat too much - 'bout $9 per gallon (I assume you're talking
US gallons) in New Zealand (erm... that's avgas I'm talking too).

I got that from:

Which was all I could find, re avgas price.

Normal (mogas)...

I multiplied by 3.8 to get a US gallon.
