Echo is a good place to go. You also have Jene's Tropicals in the Tampa area. Definitely go to Pine Island, the whole Island is just cool to visit. Many small farms that sell right out of their front yards. There is a guy between Fruitscapes and Pine Island Road, that has a serious collection of fruit trees, I think it's called Pantropic Farm, he has a small sign right on Stringfellow, and I think he is on Cristo Way if I remember correctly. Very impressive orchard!
