Maine: Scarlet Witch
While Wanda has gotten more control over her powers since she was first introduced, why not be a little cautious and have her live in one of the most northern states in the country? In Maine, she can live her life as a normal person (with Vision) and not have to worry about people constantly badgering her with attention.
I think she would be a lot more comfortable with herself and with her life if she was able to be just a regular woman most of the time and then, when people need help, she can bring out her powers and save lives.
She and Vision can eat some lobster, go to the beach when it’s warm enough, watch out for moose, and try to relax after everything they’ve been through. After the blip, they’re bound to want to spend every moment they can together and by being away in Maine, they’d be able to do that, or at least until the next villain comes to Earth and tries to destroy everyone.
Maine could be a place for Wanda to finally deal with the trauma of watching her entire family die in front of her. She’s barely had a moment to be by herself and think about everything she’s been through. She’s had to be strong and stoic for most of her life. If anyone needs a vacation, it’s the Scarlet Witch.
Wanda also has the traits many of the people of Maine display. They’re strong (you have to be to live that far north and deal with the snow), ready to fight for what’s right and to right past wrongs, and deeply cares for the people she loves.
