When you say Killeen you might as well say FORT HOOD TX.
Fort Hood used to be the largest military installation in the US, most of it is impact area.
I wish I could paint a pretty picture for you but my memories of Fort Hood are not that pleasant .
HOT,Dusty, trees dont grow tall.
When I was stationed there I went to the local grocery store and asked a cute gal, "What do you do down here for fun ?" She said get drunk and screw.....
Damn ex wife......Oh well.
