I wonder if they're a certain kind of fly? Anyone notice that? Lighter-colored...bottle flies? I mean you see some kaka-poopie out in the woods...not this time of year, but say over the summer? Bear ****s in the woods? You almost step in it? But you don't cause there's these bottle-green...yeah, there ya go, that's what I was trying to think of...those bottle-green flies you only see on bear **** and inside outhouses. Oh look at all those happy little flies.
