Thank you FC and Typhoid for taking the time to answer my question. I can see how that makes sense to get everyone grouped up so they can punch through a storm.
Now about those taxi instructions ... I decided to have a little fun and attempt to make sense out of the map (this is of course assuming like you mentioned FC there aren't any other obstacles in the way.
So if I understand those instructions correctly .... Roper is a slight pervert, so you take a taxi with Victor, you cross 12th street, and meet your Papa and grab some Whiskey and talk to a Yankee about the Yankees and then you hold up a short Mike...
Okay seriously this is what I got. And just wow. Wow. I mean ... wow.
