It does look like fire was what damaged the tree. It does have a variety of textures in there, doesn't it?
I am glad to hear that you are resting in between when you can. That repetitive motion can really do some damage! Glad your son is enjoying it as much as you. Are there people there his age also?. I like the way you play through the rain :)) There is no doubt in my mind that you will make up those steps over the weekend! You always do! Good luck in the match!
Taxes! Ugh!
A lot of the friends we play with are my son's age. In fact the older crowd is outnumbered on the disc golf course. It seems like people play with friends of similar experience and a mixed age group works well. Even having different skill levels works at times although that can be a bit more difficult.
