I dont know why other than to just understand half of what you guys are talking about but I just picked up a Douglas Dent book. Hopefully I wont have to keep pestering everyone on here about this and that, Like I have stated in other posts I dont fell tree's or is it fall, either way I have only brought down about 30 or them in the last 5 years like that most of what I do is just buck the stuff up. But I figure better to know and not need it. Again thanks to all you have given there time to my questions.
