The break up of the fairground attractions

Yesterday was last day of mayfair in Bruges. So most of the fairground attractions are getting disassembled in the evening and sometimes through the night.The scene here is one of the workers taking a pause , after the heavy work ,with a can of beer.He did look tired. Mostly i don t take picture in the front as the reality of it would vanish. If they accept the picture , they would pose and otherwise maybe getting angry. He was allready looking suspicious towards me.
Well today i dared to do my first sensor swab cleaning on my nikon dsrl. Sensor was realy dirty and an air blower didn t do the job. So after one wet clean the sensor was ok. Just 1 tiny particle but that s ok. I was allways somehow afraid to do this kind of maintenance , afraid of damaging the sensor.
