Please note that Interstate 90 will be closed this weekend across
South Dakota. This closure will allow the Federal Government free
access to haul a 200 ton piece of coal to Mt. Rushmore so that
President Obama can be added to the Presidents on the monument.

If coal had the density of water, 200 tons would occupy a 18 foot
cube. Since coal doesn't float it would actually be smaller.
