Offset mark 90* off the A mark it was "way too high".

I have always tried to personally thank all volunteers at regattas when I have the opportunity, whether I am a happy camper or not. On a few occasions I have sent a private e-mail to the OA/PRO. Sometimes its thanking them for an exceptional regatta or its offering my feedback with some suggestions as nicely as I can.

I will admit that when I have to pay $150+ for a regatta I do tend to feel more like a customer than a guest.
