re: Lebanon, NH to BR, LA

This is Baton Rouge, you want to be close.

Being at Oschner gives you many living options that are unattractive if you were working in a different part of the city (like downtown or the cluster of construction companies near Airline and Highland), but it also makes many of the best neighborhoods undesirable as well do to the traffic. Where you are working will often be cut off from much of the city for hours at a time. You're going to want to live close enough that being cut off isn't a problem. I would stay close to O'Neal, Jones Creek, and Harrel's Ferry.
