I climbed one once and I can’t believe how well you described that.An oak is one thing... but a pine tree? You got them needles stickin' ya in the face and drawin' blood, you got that bark floatin' down and gettin' in your eyes, you got a zillion branches - so many you don't even have room to go up, you have sticky sap gettin' all in your fingers, and the branches are too skinny and weak to hold your weight, and if that's not enough, the whole tree is swaying back and forth in the wind... it's a rough climb...
