These Are The Trees I Know, I Know. . .

 I was thinking of all of the different trees I’ve seen this year, when the Kids in the Hall Classic, “These Are the Daves I Know” popped into my head. You’ll just have to imagine me walking around town, wearing a tucked-in flannel shirt, and talking about the trees I know (and hardly know). 

Anyhow, here is a comprehensive list of all of the trees I’ve seen, and where I’ve seen them, while hiking this year. I will add to it as time goes on.
