My sister lives in Detroit. Last year a man broke in to her home and attacked her (the night we were at our Hubski DC meetup). She was able to grab a nearby hammer and hit him repeatedly on the arm until he finally fled. He was arrested days later, with a broken arm.

Since the incident, they've installed a more comprehensive alarm system and lighting. They've also built a "safe room," and got a new dog to accompany their boston terrier. They've gone from this:

To this:

an Argentinian Dogo

As for your question, nobody on the Hubski team actually lives in Detroit. mk is in Ann Arbor and b_b has since moved to a Detroit Suburb and purchased a minivan. I'd shout-out to him but he's at Disney World. -No joke.
