No. 9: Kansas City, Mo. With about six tattoo shops per 100,000 people, Kansas City came up in several sites we looked at as another "tattoo-friendly" place to live -- not bad for the not-so-tattoo-friendly Midwest. Why? We're guessing it has something to do with KC being the bustling center of the Kansas City metro area and the state's largest city, along with having a thriving population of below-30 folk, more than 10 colleges and universities, and a big performing arts scene.
