I live in Indy, there are 2 Trader Joes, one on 82nd street just south of Castleton Mall, and one on West 86th, near 86th and Michigan. There are 2 Wild Oats, 1 in Nora, approximately 82nd and College (it's on 82nd), and 1 in Carmel at the north end of Clay Terrace.
There is a Sunflower Market in Broad Ripple on Broad Ripple Ave, as well as Good Earth market in Broad Ripple.
Whole Foods has bought property at 86th and Keystone, but Whole Foods recently bought Wild Oats, so I am not sure what is going to happen.
If you are in the Indy area on Thursday, there is Farm Fresh Delivery (
www.farmfreshdelivery.com that has very high quality organic produce. You can pick it up at their warehouse on Binford Blvd, and they deliver to many areas of Indy.
I LOVE LOVE LOVE the Meijer organics, and they had some variety of organic veggies and fruit. The bread, milk, crackers, cookies, etc are terrific. I know there is a Meijer in Avon, that may be the closest one to you.
