RADical Days is a big beautiful thank you to Allegheny County taxpayers for their support of various regional asset organizations each year with a small amount of their local taxes. County residents are rewarded with free events, programming, and activities on certain days by individual organizations. This year the activities and events are a mix of in-person and virtual. One of today’s highlights is free timed tickets to the Andy Warhol Museum. Warhol grew up in the South Oakland neighborhood of Pittsburgh. The Andy Warhol Museum boasts the largest collection of Warhol’s artworks and archival materials and is one of the most comprehensive single-artist museums in the world. 10 a.m. to 5 p.m. 117 Sandusky St., North Shore.
