Maybe there's even somewhere relatively close to you that has a dark enough sky. You never know! A little research never hurts
I used to live in the Northwest Territories in Canada so yeah many of those photos could have been taken in my figurative sometimes literal back yard. I moved to Vancouver Island since and I've been able to find some pretty nice dark skies within a 15 or 20 minute drive. I've even taken some night sky photos from here, they're in my gallery. No auroras though they're very rare here haha.
