alwayspuzzled - I'd go with rad, jigjag and ginge for the VACANT cells - it certainly makes more sense of the second phrase, and why the 3 entries cross with each other. But I'm not entirely happy with the way Ifor 'spaced' them in the clues.
malone - Perhaps I worried too much about the use of capital letters for 'VACANT' - did that bother you too? I find it even more misleading now!
