Update!
Well, the update took a little longer than expected. I kept forgetting the sign back at home, but I ended up remembering it this time. I went out to my friends house in Porter square and while I was in Downtown Crossing, I placed the sign up on a Payphone. I quickly left the scene of the crime. I didn’t get a chance to go back home on the T that day, but I am assuming the sign is still there causing all sorts of mayhem and mischief.
