This one in MASS says she supplies 33 members. I did some digging on CSA + Texas and came up with one I know for a fact is a rip off near Houston. Two around the Austin area who call themselves 'subscription farms' rather than CSA. These only will allow 10 members, and charge $25 per week. Our growing season is different, of course, allowing harvests from the first of April to the end of November. So their members pay $800 but get 8 months worth of produce. None are biodynamically grown, but all are certified organic. (except miss ripoff near Houston.)
The reason I'm asking all this is because my cousin is a physician's assistant at a hospital south of Houston Tx. She has mentioned several times that I could be growing food for so many families. And, everyone she works with is very health-conscious and would be pretty eager to have food grown that (1) they didn't have to take time to shop for (2) healthier and fresher than in the stores. So, whether they would acknowledge or respect the fact they're helping maintain a family farmstead, as long as it's to their advantage, they're interested. I just didn't know quite how to tap into this large pool of hungry Houstonians. Nor, do I think I'm ready to do so this season.
