In all seriousness, I use a few terms to describe myself and others like me.
Firewooder. I guess if I ever moved to New England, I'd start calling myself a woodbooga.
Firewood junkie - you know you fit into this category when you realize that you're not being a safe vehicle operator because you keep getting distracted by wood (dead standing, blowdowns, deadfall, tree cutting in process, wood stacks, etc.).
Tree junkie - I think trees are interesting, and I like to share my appreciation of them with others. I've been known to talk about nearby trees and point out their various interesting aspects-- TreePointing, LOL!
