Well, it's official. At the end of this month OSgrid will turn 18, old enough to get a tattoo, go skydiving, and vote. And of course, the grid is celebrating with the traditional show-and-tell festivities on the OSGB regions.
Spaces are still available, although many are already spoken for, so don't wait too long - get building! At time of posting, there will be at least three exhibition sims, each with a dozen or more original installations, rides, gifts, and exhibitions celebrating the diverse and ingenious group of people who make up the OSGrid population.
