Saturday with a low base and quite deep Cu. Pete, Rob, Jon, Nick and myself went over the pass at around 2500m amongst the whisps of cloudbase. Quite easy on the other side, but the growing depth of Cumulus made us decide to land at round 30km. V. lifty evening flying on saturday, and once again today on Sunday for the evening flight with pilots reporting 2m/s climbs when the sun had almost gone down.
