You don't have to come to every session. If you prefer to pay-as-you go, the cost is $10 per session. We'll hang around after the discussion to chat. Feel free to bring a brown bag lunch, or you will be offered the option of purchasing a box lunch at the start of each session. We'll have coffee, hot tea and water on site. You can purchase a book, should you need one, at Viva Bookstore, 8407 Broadway St San Antonio, TX 78209 (just inside Loop 410.) We'll also have books on hand for purchase.
