Congratulations Cathryn!

Your ear tone pattern is definitely in the reverse of the rest of us. Your 13 second LEFT ear tone is for South. Don noticed that more than a year ago, yet we had some difficulty in finding your matching quakes, but not this time. So now that we have that down, we know where to look for a match for your other ear tone. You've done us proud.....Petra
