Free U2 concert today
From Gothamist:U2's Free Concert In Brooklyn Today
So it's for an MTV taping, and the show starts at 3 pm at the Empire Fulton Ferry State Park in Brooklyn, between the Brooklyn and Manhattan Bridges. It's a nice place with a great view of the river and the bridges. If you aren't lucky enough to score tickets, you may still be able to watch it from Manny B. Maybe.
