We hold meetings at 7pm on the first Tuesday of every month at the LaVista Community Center. For those months where the first Tuesday falls on a holiday, the meeting is held on the subsequent Tuesday. The Community Center is located at 8116 Park View Blvd in LaVista.

To reach the Community Center, get on 84th Street in LaVista. Park View Blvd is just south of Harrison St. Turn east on Park View Blvd and go past the lawn & garden center on the north side of the road. The Community Center is the large brick building on the north side of the road. Inside the front door is a board with the room assignments for the evening. We are normally in room 5.
