I'm in San Diego (near Mission Bay), and a get together like this sounds fun
I have 15 varieties planted, and many green fruit, but so far have only picked two from my Moskvich a couple of weeks ago (which were pretty darn yummy!). The rest are taking their sweet time getting ripe. I'm worried that black spot is going to take out a couple of the potato leaf ones before I get a harvest, but hopefully now that June gloom is burning off the plants will bounce back some so I will have a nice variety.
