'You've got to be kidding me,' I said. 'No. Seriously,' he replied, and proceeded to tell me all the different places he had put vines into the ground, including a patch not 200 yards from my door in Bernal Heights. 'I eventually had to move those plants to the Inner Sunset,' he admitted, after the politics of the Bernal Heights community garden got finicky, 'But I kept making wine from them along with the guy whose yard they ended up in.'

I bet the finicky garden politics had to do with pest control. But I have no doubt that grapes would do well here.
