hey Sue, i tried for a month and it took me nearly the whole month to locate the bugger. I have teeny hands, but so is the rest of me so i thought it would be ok. I finally found it and it was right over to one side and quite near the back, could still only just touch it. I stopped becuase i don't think it adds that much (for me) and it started to give me cramps rooting around up there. I wouldn't bother too much if you are charting and checking everything else.
