Cause that's where we'll be roaming around on a hunt to find all the items on the list I've carefully crafted for you. Remember, come to st marks at 5:30 and we'll start there. Come with your group or if you dont have one, one will provided for you. Make sure those phones are charged cause you'll be taking some dope selfies. First three teams to come back with everything on the list wins Starbucks gift cards. 

TL;DR
Come to St. Marks at 5:30. Win. Get free starbs. Meet James Redmond. Go to mass.

Love,
