On The South Florida Roundup for this Fourth of July weekend, we revisited our Memorial Day weekend conversation with Miami native Edda Fields-Black about her Pulitzer Prize-winning history of Harriet Tubman and a pivotal Civil War raid (01:08). We also examined Lucy’s Law, which strengthens the state’s boating codes after Luciana Fernandez’s tragic death (19:34). And we looked at how we measure patriotism — and why Florida keeps finishing near the bottom in one patriotism survey (34:18).
