I agree that the clued parts were (ridiculously) easy, but I found the unclued perimeter just irritating. Was looking for a more detailed connection between the three words on each edge, but so far as I can see there was nothing other than the very broad connection between all 12. Pretty unsatisfactory and so I didn't enjoy it at all. In fact found myself missing Araucaria even more than usual. Oh for a proper Saturday morning work-out!
Or is there something (re the perimeter) I've missed? That's really why I came here after completing the crossword. I'd love to be proved wrong!
