I am still in Houston. That is Houston!, Texas! and to write about overhead, over my head, above my head or looking up, I have to mention the Texas sky. Today driving home, mid-afternoon, it was cloudy and trying to rain. But as I sat at a stop light looking around, above my head, and I thought, in Texas from the ground it seems you are in a flat bottomed pie pan covered with a huge dome. On a clear day you can stand in the center of the pan, make a 360* turn and see only deep blue SKY.
In Rio, the sky is limited by the width of the street and the tall trees that line them. Even in Friburgo, as beautiful as the view can be, the sky is limited. In Arizona, the sky is the same deep blue but with its tall mountains it is a tall sided bowl covered with with what appears to be a flat blue lid.
Here in Houston, especially out here in west Houston, the high dome of the sky sits low on a fuzzy haired, fringe of tree tops. So high is the dome that even large birds are dwarfed. Man and his impact in this world seems dwarfed. No matter the time of day, or the weather the view from your point on earth is dominated by the sky.
