North Richland hills? In the dfw area there are a ton of options, including a good farmers market in Coppell, a year round Dallas farmers market, and I personally use the bountiful baskets food co op which is a volunteer only organization that you get 2 small laundry baskets of locally grown produce for $15. There are pickup sites all over the place. There are also many stores like sprouts and whole foods around.
About 1,800 miles from where I am. However, I assume you have a specific address in mind. It would be helpful to post that. Or simply go to MapQuest and plug in the specific address, then select "Directions" and put DFW as your destination. That'll give you the distance in miles and in time.
