Here is a map of the area known as 'Wrigleyville'- the area in Chicago surrounding Wrigley Field.
If you arrive via bus, as I did yesterday for the Cubs' 3-0 loss to the Reds, you will likely be parked in the Green Lot, entering the stadium via Gate K. When you exit after the game, you will see a fire station, to the left of which is Seminary Avenue. Walk down that street, and then turn left at Grace Street. Go down Grace for about a block, and at about the corner of Grace and Clifton, you will see the Green Lot, noted by the P on the map.
Do not- do NOT- continue down Seminary, even if the Cubs employee at the corner of Grace and Seminary tells you otherwise. If you start seeing tombstones on your left, you have gone too far. That is Wunders Cemetary, right behind the Green Lot. Do not, for the love of God, continue all the way down to Irving Park Road. And if a man selling water bottles has trouble telling whether you are asking about the Green Lot or the Green Line- a train route- turn your ass around and get back to Grace.
Why am I telling you this? Er..... no reason.
