There have been a few blog posts, and so on, over the past decade on a method for optimal efficiency in packing a bear can for a very long stretch that involves filling in the empty spaces with grain of some sort. Couscous was mention often, but I was thinking of trying dehydrated basmati rice. If I'm remember correctly people were claiming they could get 10+ days of food out of a Garcia can in this way
I was wondering if anyone has tried it, and what advice, suggestions and experiences they could relate.
I admit I laughed at the idea the first time I heard about it, but now it seems more reasonable in light of possibly needing to get an even bigger can (possibly exchange my weekender for and expedition) and throwing my whole dam pack system off. :-/
Also, the basmati might work well when supplemented with all the trout I intend to catch.
