It's awesome that other people in your neighbourhood like to grow their own food as well. I've been talking to the neighbour about what he's planted, so I don't plant the same, and we can share. For example, he grows apricots, so no point in me growing one. Of course that depends on him wanting to swap produce, but he seems pretty keen.

I'm with yhou on the pesticides. I think it's worse in Europe, but still. I'd rather know where my food is coming from. Furthermore, I think it's important for resilience as well - when the supermarkets had no eggs or lettuce, I had heaps.
