a way to feel closer to my friend in The Walls unit in Huntsville. If you have a fairly decent computer you can download GoogleEarth for free at GoogleEarth.com. Then enter the address of the prison in the address bar at the left of the screen and you will visually "fly" over the unit, 
and can even come in for a pretty close look once you learn how to use the controls. (It was surprising to me to see that his unit is right in the middle of a residential area.) Anyway, it can be a way to feel closer to your loved one between visits, or if you are too far away to visit very often. It helps to look down on their roof and direct your love and prayers to them.
