Yesterday was another Sunday but there were more olives hatching by late afternoon than we saw on Monday.  There were a few cahills and Heptagenias in the evening too.  Nymphing was the best bet during the day.  Nymphs that match the size of the predominant insects seem to be working best.  Today could be totally different.  We should see decent cloud cover early with the potential of afternoon thunderstorms.  Hopefully that pushes the olives and Isonychias early
