Sacramento's non-profit Soil Born Farms hosts an annual "day of learning, eating, music, celebrating community and exploring the natural world" at their American River Ranch in Rancho Cordova. They want aquaponics on display there this year. One person is already lined up to show his stuff, but they are open to others doing so as well. It's fine to use this as an opportunity to get exposure for your AP-related business if you like. They have plenty of space and access to electricity.
If interested, let me know ASAP (firstname.lastname@example.org).
