We made an early start as the temp trace indicated that the conditions could deteriorate. Great flying for 2 hours. At the pass the other side looked very good with a clear convergence to Avila. However in the West there was a large Cb at Bejar and conditons were getting too easy (to stay up). In fact, things were so flyable that one of my bee colonies decided to swarm, luckily to a nearby bait hive! Things cleared fine for the evening flight.
