Hey everyone! So glad to see there are so many interested people. Sorry for my delay in response, I was out of town without internet access. The weather looks good for Saturday so I saw bring the whole family and if you want to bring anything else, go for it.
It's hard to pick an exact location in the park since you never know who will be there and what spaces will be open, but I have marked a location on the attached map that I think would be a good spot and easy to find. I will bing a sign that says PICNIC to tape to a tree or something, though I think a group of foreigners will be pretty easy to spot. You can also try to pick me out - I have a big tattoo of autumn leaves on my chest, that's the easiest way to spot me.
Basically, just walk down Sarmiento and cross Libertador, that first area you hit is pretty big and spacious. If it seems to be crowded with people that are not the expats, walk along the lakes and you are sure to find us. I'll be there a little before noon, see you there!
