As someone from Michigan, the UP, while great in its own right(just as the rest of the state of Michigan outside of Detroit and it's suburbs), is very much being idealized here.
I live on the west coast now and the beauty simply does not compare. I can't speak specifically for California but even SF, its surrounding hills and even the time I've been in LA make the UP pale in comparison.
We're talking about dirty rural communities with no mountains, and no oceans- forget about jobs. Oh, and I hope you like hot summers and freezing, feet-of-snow and ice winters.
There is a reason some places are more expensive than others.
