While sitting on the airport tarmac, other passengers and I were pondering how we would make up the 2 hours lost on the ground....whether by having tail winds, or flying the direction opposite the rotation of the earth.

Since those trees that are said to be 5000-6000 years old were found in Utah, does that mean that the "Methuselah" tree located in California (which is about 4800 years old and still alive) is just another old tree? is its title taken? here is the Wikipedia link for the "Methuselah"

P.S. If you have google earth on your computer,
The Methuselah is posted and it includes a very good picture

Why would two quadrangle maps with the same scale and same 71/2 minute measurement be different in size?

One map is from Louisiana and the other is Mount Pleasant Michigan. Why would the map in Louisiana have a wider area grid on it than the Michigann one?

The reason for sea waves was told to be the gravitational pull of the moon. Then what about the effect of the gravitational pull of the Sun on sea/oceans? If so, why not each and every lake also produce waves?
