I liked the bag pipes. There were also lots of police departments and fire departments that marched, including some that came over from Ireland.
There were lots of random people walking, like all of these people dressed like Star Wars characters.
Basically, it was good to go to this parade to see what it was like...but I am not sure I need to stand in the freezing cold again next year, unless we have visitors that want to see it. It is probably more fun to be in one of the kajillion Irish pubs in Boston if you can get into one...Even at 10 in the morning, the pubs had huge lines outside!
