good plan RR.
want a recipe for turtle soup?
a pair of goggles would help you greatly but one must consider this.
what environment do u plan on using them?
i live in BC and i know one thing.. majority of lakes are glacier fed and are freaking cold.
i swim along the coast in the summer when the water is warm, there are a few lakes around here that are warm enuf to swim in during most parts of the year.
goggles usually have a lite tint to them, so they may serve other purposes as well.
especially when it snows and you have to cover a long range or distance. the goggles may help protect your eyes from snow blindness.
perhaps the rubber straps from the goggles can be removed to make a make-shift tourniquet in the case you happen to have injured yourself.
do you think its possible to use the goggle lens to make a fire? in a pinch it'd be great. or perhaps you can use it to hold a small pool of water to act as a magnifyer. i remember learning from my dad that you can make a fire with a zip-lock back filled with water which acts as a magnifyer so the same concept may be applied to the goggles?
when worst comes to worst and you've lost your knife the plastic lenses can be ground down either into a knife (most likely crappy) or make some sort of shank (like the prison kind) which can help you hunt. perhaps turn it into a spearpoint?
if your in an environment where fresh-water may not be readily available you could try catching dew drops in it off greenary in the mornings. may not be enuf water to help you but might be just enuf to survive.
i know that theres certain species of birds that are attracted to shiny things so perhaps you can even use it as some sort of bait to attract birds?
if you have paracord or a fishing line you could even turn it into a spoon/lure for fishing.
other then using them to collect food i think u can use then for a few other things such as the stuff i've listed above
thats about all i can think about now will post later if i think of more\
cheers
