Donald, I really like the fog pictures. Once you get home you might try brightening them up a little bit. The one of the river and tugboats could be a great print on the wall.
Also, I know you're shooting from a moving car in many of these, but you still seem to be missing the focus just a little bit. Unfortunately, focus is something that can't be fixed later, so spend an extra second to make sure you have focus and are holding the camera still.
Keep up the good work! I was born in Baton Rouge and also lived in Houston and Lake Charles, places you have just been.
