Event Report

Mark originally arm chair planned this event and then went on another holiday. David and I spent a few happy hours in the woods checking his ideas on the day after he blitzed the Milton Creek KNC in February. This kept Mark's overall strategy intact with just a few minor changes to half the control points to reflect the situation on the ground. After that it all went well until I lost control unit 101 on the day, and then the finish unit died on the night. I manually checked everybody home and people gave their own times. All good fun.
The pub was very convenient and after three conversations, a dozen emails and five alternative pre ordering and other strategies had been cycled through they kept the kitchen open late specially for us and all who wanted it got hot food. Dave Cave even blagged a dessert. The fish and chips was great value and looked amazing. Thank you to the team at the pub, I saw only clean plates.
Thanks also to the school for use of the car park, for the princely price of two boxes of M&S biscuits, although to be fair they only asked for one. And a big thank you to the land owner for having us, and to Richard Field for arranging land permission.
All seemed to enjoy the head scratching challenge that Mark had dreamt up. See you all next week for the final KNC event of the season.
