I am getting lots of alerts of NO problems at all. Inside Penn less crowded than typical Friday. Two co-workers just went through and reported that although crowded very orderly. If you are using 7th avenue, walk on the East side. Walk to 32nd. The police open the barricade when the light changes. Despite what I read that attendees of the Mass, were supposed to be inside MSG by 3:30 PM, looks like the line to get inside MSG is still queued outside; west side of 7th ave all the way to 23rd st.
The only open entrance on the Eighth Ave side is Eighth x 31. Not sure abt Seventh.
