If its laying down I'd take it there's a difference if your taking wood that is still standing compared to stuff that is already laying or is dropped. No need to let good wood go to waste. That's just like that wood I got the other day when I did my post the whole tree blew over root and all and it was on rail road ground well the tree came down across the dirt road and all they did was cut it in half and push it aside to let it rot.
that's what I say!... deadfall or just fall... if its within reach... I reach!
