I've seen one outdoor shop that was willing to open gallon Coleman cans and sell enough to fill a fuel bottle (Pinedale, WY), and yes, that was in an area with lots of hikers/climbers/cyclists.

Dragonflys are great, simmering ability and temperature control are the wave of the future in cooking!. Mine came with a jet that lets me use kerosene (or diesel), and it will run on unleaded if I have to.
