You've been hearing tons about it; now, it's time. Be part of turning the Pearl District, which just a few weeks ago was full of boarded-up, unused buildings, into a lively, active community this weekend as part of an an initiative to offer citizens a clear vision of what Tulsa could become through community redevelopment and urban revitalization. Local business owners will move into and operate out of these spaces for the weekend, and plenty of kids activities, live music and community organizations will keep Tulsa families busy all day Saturday. Each year, TYPros plans to pick a different part of the city to shine a spotlight and spark conversation. Through 9pm tonight; see below for tomorrow's Polishing the Pearl activities.
