Barking mad.

Too hot and too lazy to go anywhere today. Anyway it's Sunday, day of rest and all that. No unexpected opportunity or inspiration presented itself.
However, it's amazing what is just under your nose. This is the main trunk of my Damson tree. It may have something to do with the five cans of cider I have already imbibed but I think it looks insane.
I pass this tree several times every day and have never really looked at it.
We have had this tree forever (inherited it from the previous owners). I only discovered it is a damson tree when it produced fruit unexpectedly five years ago. It has fruited twice since.
If it fruits this year I am going to try to do something with the damsons.
Any suggestions?
