When we moved into our home here, we wondered how many people we could sit around a table for a sit-down meal. Thanks to an open-plan layout, we thought maybe a lot. Of course, we would need more chairs and more table than we have.
I've mentioned before about my love of large but curiously specific numbers on signs. This was another one - spotted in the Empire State Plaza concourse in Albany - the second picture is the view from the sign's location along the concourse. I think a sit-down meal for 4830 +/- 1 probably takes open-plan to a new level.
