The Arizona chapter of the California Rare Fruit Growers is hosting the Festival of Fruit this year (which hasn't happened in a decade!) from November 3rd-6th. This is the year of the Pomegranate... a rare fruit that happens to grow really well in Phoenix. There are going to be some really interesting classes, three days of tours, fruit tastings and people coming in from all over the country with an interest in rare fruit. Tickets cost $35 per person until October 5th and then the prices go up to $45.
