I assume this is a duplicate of the following:

That one did not have a location attached, so it can't show up on the map. I fixed it for you, so we can presumably delete this one.
We are having our usual South Bay meetup this Saturday. I put up the notice some time ago, but it isn't showing, so I am putting it up again.
