That’s right. But I thought the “__ R D” all meant something specific.
It wouldn’t surprise me if there was an urban myth which had turned the thing into a three-letter acronym. But nothing I can find suggests any other name than Orchard Field, and it seems pretty obvious that the R and D come from that. Occam’s Razor, and whatnot.
Cecil’s razor, too 
And I knew that we’d done this before. Plenty of good info there.
