Beginnings

One of my most vivid memories as a child is resting in the back of my parents station wagon while driving back home to the city. The stars were so bright and the sky so black as I peered out the window. In grade school, my parents bought me a 4 inch Tasco reflector for a science project. Focusing on Mars reminded me of the last scene in, "You Will Go to the Moon", one my favorite books as a tyke. Mars was so small and so distant and so tantalizing.
