Hey mate!

I'm also from Scotland and moved to Australia over 5 years ago. It was the best thing we ever did!

Trav has given you some great advice, nothing to add really. It's a great thing to do. I'd seriously think about the UK, you're on the doorstep to some amazing places around Europe - weekends and holidays away would be soooooo easy! Also, you're close to America, it's only really an 8 hour flight from the UK.

America can be hard to get into unless you have work lined up - maybe your DH could see if any companies would sponsor him to work in the States?

Good luck!
