Cold front cleared through overnight leaving us in a cold blustery airstream. It was aerotow only due to the wet field. The tows (particularly going over the ridge) were exciting, the stop for lunch coincided with the only shower to fall on the field until the vigorous trough came through at the end of the afternoon. There were numerous flights of about half an hour, the longest going to Liam and Paul C at 41 minutes. VG soared for over an hour. Lisa kept warm in the back seat.
