Ok first, lemme say I'm horribly jealous, cause I've been job hunting for a year - although I haven't been willing to relocate. Good luck to you.
Software company should be pretty stable here as technology has taken the lead in the "triad" area.
I was born in NC about 1 hour from Hight Point. The furniture industry has dissipated along with textiles, etc. and is not as dominant as 20 years ago.
It get [I]really [I]hot here in the summer, and about 20 F lowest in winters.
I don't know the cost of land/living in AL, but be careful here of all the new contruction homes, developments, etc. EVEN if they call theirselves somewhat rural.
IMO, look for a quality older home and property if you come here.
Let us know what happens!
