funny picture... got spades, anyway with regards to the
topic...
first thing... can u build a fire? do u have a knife? if there
water?
if yes, they do those camping thingie tat suspends your food to be
roasted. else can find bamboo, dig out the inside, and put your
food inside to roast. or wrap in banana leaf.
fish can be eaten raw, juz make sure to gut the bigger ones. alot
of innovative ways to fish too, without equipment.
if your really interested in this topic, check out Man vs Wild, on
Discovery Channel. this "crazy" guy, Bear Gills gets dump some
where in the world, with a knife, flint and a bottle of water, he
has to survive and find a way out.
