sweet caroline good times never seemed so good back on the streets of boston, an eerie quiet on normally busy streets. for megan keeler returning to this seen after witnessing the explosion brought back overwhelming emotion. i think it s just hurting me now, to be honest. reporter: what does it feel like? i feel really badly for everybody. i m proud of this city. but it s people are waking up today, and their lives are very different. certainly an emotional time for a lot of people in this city. also hundreds gathered last night on the boston common for another vigil, such an outpouring of support. i know some of the offices behind us and the crime scene will be closed, but will the city mostly be back up and running? i think that s the hope.
