A wonderful opportunity to see free theater during the month of October is just a click away.
Nationwide it is "Arts and Humanities Month" in which free admission will be offered at art museums, concerts and theater.
This is the link to theaters offering free tickets to performances in Orange County. This is a great opportunity to get out and see good professional theater.
Go to the blue bar and choose "Th emes" (strangely enough the offer isn't under "Free events")
Select "October Free Night" under themes menu
Click "Reserve your Tickets Now" and you will see a selection of performances available.
