Okay you are going to meet me at a books shop on Chestnut Street. But first make your way over to the United States Mint which is about a block south and a block west of where you are at. Okay now go three blocks south and you'll be at Chestnut. I am not 3 blocks west of where you are.  I'll be on the southeast corner of that intersection. One block before you get to the book store you will pass a Public Ledger Building.
