Blackflies leaving da house

Just went overnight to the cottage to start the pump and fix everything up.  Avoided going up the long weekend, since the traffic is always horrible.  It was really nice, and we thought the blackflies would be as bad as 2 weeks ago, but then we saw the dragonflies.  It takes them a good couple of days to wipe out the blackflies, and it looked like they were half-way through.  We could sit outside, but with a fly candle-lamp.  Really nice.
