It is awesome, the weather here is turning out to be nice now, a lot of people are nice but there are some jerks like most places, but it also depends what part of Wisconsin you go to, the closer to the lake front the colder.
It's just like any other place. It has it's good and bad points. Some citizens there want to move away, while other's wouldn't trade it for the world. I suggest going for a "visit" before deciding either way. Good Luck
