Today I played 2 1/2 hours of pickle ball. 
Walked around the property looking for a picture and all I came up with was the 3 courses. They always stand in a pack of 3.
This evening i have spent a lot of time writing down and photographing all my camera gear. I am thinking of taking it in the a camera shop in Seattle and selling it and then buying a new mirrorless.
I am however still not sure which ne. They all have good points.
Nikon z9
Sony a7r or 
Canon eos r5
Any input would be appreciated
