This thread and the addition of so many new people has caused me to wonder whether the site could use a new section of local sources by country/zone/metro area. For example if you're looking for a local source of Actinovate or something less shipping friendly (like rabbit manure.)
I know the gatherings area has some geographic breakouts, and one of the lovely things about this site is how global it is... but it might be beneficial to have a few areas where someone can ask where to get coconut coir in your state.
I've started searching for a group of gardeners in my city, just to get other specific feedback and share ideas. There is something through Meetup, but it's a little broader than gardening, it's organic, sustainable living, etc. Also my county extension does offer some classes and such; I hope to attend some.
This was also prompted by finding a Craigslist post for llama poo out in Brevard County (FL). Must admit I'm interested!
