Are there any places in/around Corpus Christi for yummy fruits sold by street-side stands, especially mangoes?
We don't grow mangoes in South Texas and strawberry season is the spring so anything you find will not be local. There are fruit stands dotted along Hwy. 77 heading south toward the Rio Grande Valley. Lotsa melons, lemons, limes right now. Bluntzer Fruit Stand is a good one in Robstown, north of Corpus Christi.
Look into Fruit King as well... they have several stands in the city.
