What to do when you want a job teaching, but the only available jobs are away from home?

I received an email from a principal of a school in Queens looking for a certified, experienced ELA teacher.  The school is middle grades (6-8) and seems okay.

The drawbacks are many.  It's an inner-city school which means there are a bucket load of troubles.  Kids who don't want to learn or do work.  Crowded classes where some may fall through the cracks.  Further, I'd have to live away from home (there is no commuting from the suburbs to Queens).  That in itself creates a bunch of issues.  Can the marriage survive it again?  Can my son handle it?  Do I want to give it a go?

I wish this were an easy decision.  It's not.
