My parents were from SD, they would send me back there every summer to work on my relatives farms,think they were trying to make me more manly. It didn't work but at least I got to have different people pick on me during the summer.
Last time I was back there was 4 years ago for my oldest brothers funeral that trip convinced me to never go back again. Nice enough people but too much religion and "family values". Its nice place if your a white straight christian male but if your LGBT, Native American or other race not so much.
