well i keep alot of my "waste flakes"
if its big enough to crunch a small flake from i keep it
anything else goes int ot my garbage and i let the city dispose of it for me
i done worry about future archeologist finding it,what 10000 yrs from now
so by that time it will be considered ancient no matter who did it
as far as the anti freeze thing goes with animals(or even people)
very very bad way to die
if you ingest it(at doesnt take all that much)it will cause your kindeys to shut down(and other organs)
its a painfull agonizing death
ive seen people put dishes of it out for the rabbits and squirrels to drink here in town
when you see one dieing from it,you will never do it
an arrow is much quiker and much more human way to go
beside dog makes for a good meal
why taint it with antifreeze
