Time again (albeit a little earlier than usual) for your annual offering of free admissions from the Allegheny Regional Asset District. ARAD uses a portion of the county's sales tax to support libraries, parks, arts groups and sports facilities, and its annual multi-week thank-you to taxpayers is RADical Days, Sept. 20-Oct. 13. Admittedly, some RADicals Days stuff is usually free anyway, but lots of it isn't. On Thu., Sept. 20, for instance, entry to Phipps Conservatory and Botanical Gardens is free. On Sun., Sept. 23, you can fly free all day: visit The Andy Warhol Museum, Carnegie Science Center, Mattress Factory and floating enviromental classroom Riverquest, or take in the "Rising Stars" concert at Pittsburgh Opera or the New Hazlett Theater's full afternoon of live music, film and more. And if you want to balance out all that art with some sport, on Sept. 27, take one of six free hourly tours at Heinz Field. RADical Days continues with lots more through Oct. 13. See a full schedule at www.radworkshere.org. Bill O'Driscoll

That hot theatrical ticket Midnight Radio returns for its fourth season.

The Bricolage troupe includes Jason McCune, Wali Jamal, Elena Alexandratos and Bria Walker. Bill O'Driscoll 9 p.m. Continues through Sept. 29. 937 Liberty Ave., Downtown. $15-25. www.webbricolage.org

If you were a kid in the Ohio Valley in the 1970s and '80s, you wanted to be Ray "Boom Boom" Mancini. A handsome Italian pug from hardscrabble Youngstown, Mancini captured the hearts of the valley and the nation. In his new book The Good Son: The Life of Ray Boom Boom Mancini, biographer Mark Kriegel paints a stunning portrait of the fighter and the man. An immensely talented boxer, Mancini is forever linked to one of professional sports' great tragedies — the death of Korean fighter Duk Koo Kim following a 1982 bout with Mancini. Kriegel's brilliant chapters about that episode are the book's most compelling. Kriegel and Mancini attend a book-signing tonight. Charlie Deitch 7 p.m. Barnes and Noble, 100 W. Bridge St., West Homestead (The Waterfront). Free. 412-462-5743
