Both Saturday and Sunday were hot and sunny. We were in the shade provided by the canopy for most of the day, until mid-afternoon. There was very little breeze. Traffic was busy and steady on Saturday, and a bit sparser Sunday. Many people had good questions. There was music ion the stage opposite us for most of Saturday, and it was too loud. It was better on Sunday. I think that, because of this, no-one tried any of the instruments. I think of events like this as "planting seeds", with any results not visible for an unknown period of time.
