Help the Environment, Plant a Bush back in Texas!

"I place economy among the first and most important republican
virtues, and public debt as the greatest of the dangers to be feared.
To preserve our independence, we must not let our rulers load us with
perpetual debt."
-- Thomas Jefferson, third US president, architect and author (1743-1826)

"Give Peace a Chance" -- John Lennon (9 October 1940 – 8 December 1980)

Peace may sound simple—one beautiful word— but it requires everything
we have, every quality, every strength, every dream, every high ideal.
—Yehudi Menuhin (1916–1999), musician

If you think you can, or you think you can't, you are probably right.
—Mark Twain

"Art may imitate life, but life imitates TV."
Ani DiFranco
