The Scout Shop here sells the sardine cans, if you have one of those near you. 
Nope, no Scout Shop here.  That's ok though.  I can wait until January.
For now, most of my travelling is in the car, and I carry my full kit in the
trunk along with my snowmobile suit and extra clothes in the winter.
My current focus is getting a little wood stove.  Have a Kelly Kettle, and
while it's great, I see the need for a back up to my Brunton multi fuel stove.
Next week, I'm going to make a large hobo stove from a 1Kg coffee can.
Have seen a few now, and like the design.  
Cheers
