I grew up here in Dallas. Currently the job market is pretty sad. I have been looking for work since June of this year. Not much in the way of IT/Telecom jobs or general office type temporary jobs. Not sure on the teacher market. I have ex co-workers that have been out of work since last October that still haven't landed anything. I am willing to do pretty much anything at this point.

It's getting to the point where we might end up losing our house if I don't find something pretty soon.

Since you aren't wanting to take an ice chest probably best munchie foods would be nuts/seeds, jerky maybe some celery or that type. Just something to munch on between cities/towns would probably get you through most of it

Hope you enjoy your trip and good luck in your re location search
