The Philadelphia-Serengeti Alliance (PSA) invites you to participate in our debut fundraiser, “The Top of the Hop,” to be held on Saturday evening, October 19, 2013, top floor of Hopkinson House on Washington Square, Philadelphia, PA. We are planning a wonderful evening of African food and music, with over twenty raffle items that have been donated by Philadelphia businesses and individuals — all overlooking a fantastic view of Center City and the Delaware! PSA is an all-volunteer organization officially established in 2012.
