Many thanks to aristo, tyke, paulh, paul, and dorrien for your votes, and to jono, faiton, ginge and FJ for the mention - all very much appreciated.
Thanks also to BBM2 for a great word to clue and my prizes. Marty, are you still waiting on your knee operation? If so, I hope it goes well.
Hoping to come up with something to capture the imagination next week.....
