Note to self: Never go far from home ob March 17.  The trip to 23rd Street was fine. The trip from 23rd and Sixth Avenue yo 55th Street around 10:00 took an hour because of parade traffic and all the people dressed in green, many of whom were drunk.  When I left City Center at 12:45, I decided to take the 104 bis hom e on 8th Avenue.  I waited 45 minutes for the damned bus to arrive because of traffic backups.
I am home and really pissed: you'd think after how many effen years of this parade, the MYA and NYPD could have some plans about the traffic mess.
