The plaque goes down well with the residents too: I spot bunches of people gathering round it all afternoon, pointing and scratching their chins thoughtfully. A full description of the revolutionary experiment done here is finally available. Together with new displays inside the primary plantation residence (a beautiful colonial-style building, like many on the island, with elegant floor tiles, grand dining room and elegant carved staircase that spirals to the high ceiling) it makes a great tourist attraction for visitors - and this is going to be quite the local hotbed of general relativity!
The presidential party runs inside as the heavens open again. The plaque survives its first rainstorm, and at least looks solid enough to last a long time. We leave epoxy resin to cover the few exposed bolts, and rejoin the party, now continuing with music and dancing on the covered veranda.
