Wish you the best, wherever you end up. I did something similar when I was younger--wasn't getting anywhere in my home town, so I woke up one day and decided I'd move to the nearest "big city," completely on faith. Best move I ever made.
My problem is that I did the big move last year...and haven't found a permanent job here. I had a temp one, but it ended in December, and since then...nothing.
At this point, I have no real ties here except with my roommate (a fellow FReeper), and she's leaving soon as she's getting married (to anopther FReeper), so I'm going to take my chances again.
Maybe this time, things will work out!
