I grew up in the south suburbs of Minneapolis. Fantastic city. Wonderful people. Good Economy. Reasonable politics (Both Liberals and Conservatives tend to hold more moderate, nuanced views of issues, and its generally considered impolite to push your religion or politics on someone else.)
And it’s cold as bloody hell about 4-5 months of the year. Oh yeah, and another 2-3 months of the year the mosquitos are a real issue. April and May do tend to be really nice.
Southern California, and in particular coastal San Diego does deserve a weather premium. It’s just amazing here that I can go running outside in late January. You never worry about your car starting in the morning. I love the nice weather here, and it was part of why I chose San Diego for grad school.
