Wow! Big change indeed!
It sounds like you have thought it through, I'm sure it's the right move for you, your reasons are sound and even though there's obviously a wrench, it comes across like you're really happy about the decision.
Best of luck, and I hope to see you next time I'm in NYC! :-)
Thanks @cryptogee and YES please come and visit soon, would be great to meet you! And of course you (and family) would be more than welcome to stay at our place.
