can't wait for this all to begin.
in regards to your question of waiting in line. You can always hang out at the train station. Things will be blocked for lines for DMB. usually at Bruins games there is a line starting at the escalators until they let people upstairs. But in previous years, they also didn't open the doors to go in until a certain time. But not sure how they work the concert. be prepared to wait outside just in case. one side is more of an alley way with a roof over it so bad weather you want to go in on the side near the "T" good weather, doesn't matter. But id say either or. If they do let people inside and you can wait at the escalators, that line will build quick. so just be prepared for either situation.
Good Luck!!! The Garden is one of my FAV places... can't wait!
