Only regret things you haven't tried, and had an oportunity to do so.
You are young, healthy, not bound to something. go for it!!!
If i didn't have a family here to take care of, and wasn't engaged soon to be married.. and was in your situation..
I would of packed up, rented out the house, and moved down there for the two years or so.
And lets just say you do fall on your face and realise you don't want to do that job any more. You earned at least 33k down there i'm sure .. you could still have your car even if you don't its replacable. come back here kick out the renters, move back into your own place, and start looking for a new job. hell they might even hire you back, because of your experience in the company, they might even hire you with higher pay and different position.
Leaving a company is not always a bad thing for you, because they will always have new open positions down the road, and with you knowing their business you can always apply, as long as you leave on good terms and don't burn bridges behind you.
Stay positive, stay allert, keep your eyes open, watch your back and the hand in the pocket where the wallet is....
good luck!!! we'll miss you..... but you won't be a stranger here, internet is world wide
