Man, I never get thick rings like that. My rings are almost always paper thin. Super aggravating to chase, but is supposed to be denser better wood with thin rings, right? I don't know. Nice score for sure, those should definitely make some nice splits and staves. You know that pith hole in the middle with all the other little holes? Well one year I cut some good sized osage tree, and after splitting the upper section of it out I saw a bunch of pith holes going threw the wood like those. For some reason I thought they were bug damage or something so I deserted all the staves from the upper section of wood, only come to my senses a year later after they were actually infected with bugs. Man I beat myself up all the time for that.
