Rhapsody in blue

A slight easing of the heat today, some of the local streets were closed to car traffic and there was much animated eating and drinking being done by the locals. Wasn't sure what is was for.
We continued our steady progress through the local produce (extra one), others sought shelter where could find it (extra two), while yet more took part in an anti-vaccination protest (extra three). I did hope  think they'd be stiflingly hot in those outfits.
