Gosh! Had to comment when I saw the video that Ghostrider shared. That was taken over 11 years ago by my husband on our first ever visit to Shetland - what a blast from the past! We've been living here for over 8 years now. Proof if it was needed that while the weather certainly isn't for everyone, it also doesn't put everybody off. I can't comment on how easy it would be for you guys to live up here (not many of the buildings are wheelchair accessible as they're all pretty old & pre-accessibility planning law), or whether you would experience racism - generally I have found Shetland to be a very welcoming friendly place to be, but there are idiots here, just as everywhere else, and it's not a hugely ethnically diverse community. I hope whatever decision you make you end up somewhere that works for you guys.
