My Grandpa would have poured it out on the gravel drive! My dad probably would have done the same thing, only, he would say "giving it back to Mother Earth" as he did it. My have times changed! BTW: i have a friend that poured a soup can full of gasoline and stuck it under an upside-down metal barrel. He ran a cannon fuse a distance from the soup can and out the barrel and down the road. He let the hot summer sun bake the whole contraption for a while, and when he thought the gas was well evaporated, he lit the fuse. He said the barrel shot in the air 100 feet.
Anyways....... I'm waiting my turn in the doctor's office, and I needed something to do, so I'm just sitting here telling stories..... you're welcome!

Sounds like a North Korea space shuttle launch.
