yeah, 3 comfortable days, though I've stretched it to 4, i think with great discipline and careful planing someone might be able to go 5 days with 1 high calories meal a day, but thats just me thinking the impossible, lol. i guess i'm just in denial, eventually ill have to surrender to the large canisters.
for the fish i was thinking of using bushcooker and pot to make fish soup, that would be the best way to get all the calories out of the fish. it would get repetitive but 10 days is not to much time for roughing it out. plus after that, the "back to civilization" hamburger would taste that much better. lol
