I am starting my JMT hike in August with a group of 5. We will resupply at Vermillion and Muir Ranch. I always repackage my food for my hikes to cut down on waste, bulk and weight.
The problem I have is with the foods I open and repackage; like dehydrated meals, nuts, etc. Since they are no longer sealed they won't stay fresh for as long as it takes to mail, etc. I would like to pack my canister with the food beforehand to make sure I have room for all the food. I also do not want to leave so much trash at Vermillion and Muir Ranch. I was thinking of resealing all of the opened items using a vacuum pack machine. Naturally, the unopened packaging could remain as is.
What have you done or what what you suggest?
