UWE turned up in force for the first day of their week, and although visibility was pitiful to start with, Mike kept them entertained with a version of the course introductory powerpoint show until we were able to get started in a brisk and chilly south-easterly. By lunchtime we had all cheered up although Sarah had already eaten all her sandwiches whilst sitting in the winch. Flew two PWs and a K21 till nearly six before we'd had enough for the day. Some good climbs though Richard discovered some interesting and persistent sink at one point.
