Kefir grains wanted, for culturing milk and/or sugar water

Hi,

I want to start producing milk kefir and water kefir at home, but the kits are expensive and have to be mailed. If you have any healthy grains that you are willing to give or sell to me, please let me know. I can pick-up if you are within biking distance of Escondido Village. If you know of any local places that sell the grains or starter kits, that would help too.

Thank you!
