Mark,
If you didn’t have a computer handy, you wouldn’t be on here.
AirNav shows two routes home to refuel with Mogas. One goes thru 1E7 at Amarillo $2.95 price, 4 NM further than a great circle route,and the other goes thru MDF at Mooreland, Ok $2.48 price, 43 NM further than a great circle route. You do the math.
Have fun!
