This weekend in Philly: Learn how to salsa at a location  that overlooks a lake at a historic boathouse in FDR Park; celebrate Painted Bride’s new West Philly location with a housewarming party; or, get your bug on at the Academy of Natural Sciences’ annual Bug Fest. There are plenty of fun things to do this weekend in and around Philly. KYW Newsradio’s Holli Stephens has the details on The KYW To-Do List.
