Both Pishta and myself are located in Tustin as well.
Have you gone to the enderly center on 17th street near the 55fwy? It's from 7am to 11am every first and last Sunday mornings of each month. Called the million dollar breakfast cruise.
Also Wednesdays at the sports bar on Tustin ave from 4 to 7pm
That's just two of the regular local events I know of.
