Although there were large build ups of  towering cumulus to the south (cancelling the day at the Nationals in Pedro Bernardo), our region seemed to be fine till some Cbs later in the afternoon around 6 to 7pm.  Quite rough conditions and climbs to over 3000m.  Ralph stayed with it and made the best of the day with a flight returning from Barco and then to the Pass for around 60km.
