What is "co-housing" -- and why has it become so popular so quickly in certain parts of the U.S.? And how is it different from assisted living, or nursing-home living, or communal living? On this edition of StudioTulsa, we speak with Melanie Fry and Jane Zemel, two Tulsans who are involved with the still-emerging movement to create a Tulsa Senior Co-Housing community. Fry and Zemel tell us all about this movement, and about a free-to-the-public, 10-week course that people can attend in order to learn more about the co-housing philosophy...and about whether and how it might be developed here in Green Country. This course is called "Study Group I: Aging Successfully, Aging in Place" -- and it begins on Tuesday the 13th at 6pm at Church of the Madalene in Tulsa (located near 22nd and Harvard). More information about this course can be accessed at TulsaCoHo@gmail.com, or at this Facebook page. Also on our show today, commentator Barry Friedman is thinking about the proposed Oklahoma One-Percent Sales Tax, also known as State Question 779, which voters across our state will decide on in November.
