One of my other hobbies

These are Koi Carp which I have had for many many years.The pond I dug when I had much more energy and less sense I think?
It's nice to be able to sit and watch them swim around on a nice Summers Evening.I have been known to get in with them a few years ago but not now? The water temp is pretty good @ about 22c,but I'm not as hardy as I was?
These two are the biggest at about 600-800mm long and I don't know how heavy.But heavy enough to hurt my back no doubt? lol

Something a little different for 502?
