Yesterday's rain had drained from the field sufficiently to enable aerotows, although there was low cloud and drizzle for the first half of the morning. Once we got started the low cloud was coming and going just out of sync. with the aerotow turnround. Finding odd holes in the clouds, there was zero sink above cloud tops - we just had to be a little cautious with the closing gaps. Only 5 aerotows but at least we all flew in one seat or another.
