How are Somerville and Tylenol™ related?

You'll know if you've ever tried to drive in Somerville, MA. Setting out to purchase yet another piece of DJ equipment from craigslist, I briskly glanced over the google maps directions to this place and naively set out to drive there from memory. According to Google, it was a 15 minute drive.

An hour and ten minutes later, I am still aimlessly wandering around the sign-less spaghetti of streets that scream at all outsiders to leave, if they can, and never come back. And then I found myself trapped in the middle of this intersection. How many Tylenols™ do you need to just look at this picture?
