No. 10: Los Angeles, Calif. Home to some of the most popular tattooed celebs, like Angelina Jolie and Kat Von D (of "LA Ink"), Los Angeles boasts about 150 tattoo parlors within 10 miles of the city center. (Heck, we counted 15 in one of the country's most famous tattoo "strips," Venice Beach, alone). Its surrounding area also plays host to some of the country's largest tattoo expos. And while the amount of people living in L.A. (we're talking millions) hurts their per capita ranking (which is about four shops per 100,000 people), as one tattoo lover we found put it, L.A.'s tattoo-friendly "vibe" is hard to find elsewhere.
