Possibly moving... opinions wanted

OK OK so this isn't set in stone yet, nor has the offer been made but I would love to here different opinions on this (Jennifer, I know yours) LOL. So, after much consideration my husband quit his job a couple of weeks back to go into another line of work, now he has been in the transmission industry for well over 9 years now so this is what he knows(like the back of his hand). Anyway he is now in his new position and and having to learn to love the office environment ( he used to be southeast sales so needless to say he was on the road ALOT!) it is taking some getting used to on his part. Well he gets a call in the last week or so from his old companies competitor asking him alot of questions and wanting to know if they could meet with him to possible offer him a HUGE position and double his salary to move to (drum roll).................ALABAMA!!!! Now let me just tell you this is a once in a life time opportunity for him and needless to say I would go if and when he is offered the position. I do not want to be the reason later in life that he didn't take this position. I stand behind my husband 100% and say go for it, good job. Now on the other hand I have 2 young girls and my family (mom, dad, sister, brothers and nieces) are all in NC. So of course this puts a bit of a bind in this situation.. Both my brothers and my sister say GO because if it was one of us we would be long gone... although we will miss you!! Some of my friends also say go and yes they will miss me! On the other hand my mother is FLIPPING OUT, making herself sick over this even though when we were all younger she did the same thing moved us from Pennsylvania to NC for no good reason though. My question is, if put in this same situation would you go? or would you stay? Rob will be flying to AL next Friday to interview and I will keep you all posted!! until next time.....
