Sure, it would be nice to have a roof deck in Cambridge so you could invite 100 of your closest friends over for an al fresco dance soirée. The Dancing on the Charles parties at the Marsh Post American Legion are a little closer to reality. On seven Saturdays this summer, Soul Clap and other local DJs fueled the dancing crowd under the stars.
