I'm assuming the $2 doesn't include fuel for cooking what you are getting and you still own a stove,a house,access to potable water,and a pot to piss in?
If I'm in Jamaica,I'd be getting fish and limes,If I'm in Mexico,definitely beans, scawny chicken(I think they said it was chicken

),and probably bad water...If I'm in Hawaii it would be fish and rice.If I was in the midwest,probably some kind of cornmeal and whatever else grows there.
If it's wintertime..probably a couple dollar burgers because it's gotta be warm in the fast food joint...

If the clouds are so thick you can't see the top of the mountain from the bottom..what the heck makes you think it'll improve the other direction!Realityguy
