The TMA annual potluck is schedule for October 30. Join us at for good food, conversation, board elections, awards, and presentations by guest speakers. Festivities start at 5 PM at Painted Hills Church. (Look for the barbeque!)
Changing of the guard
TMA President Ed Hendel has stepped down after 2 years, to spend time with his (growing!) family and business. We'll dearly miss the energy and precision Ed brought to TMA's causes, from I-11 to Project Blue. We're also excited that Vivian Harte has stepped in as the interim president!
