Come on out. We'll let you pack a 660 or a 390 with a 36" bar, wedges, gypo jugs, maybe a set of jacks, a few tools, along with your water and lunch of course up and down some of the terrain we work on. It's not really steep enough to be called vertical, not everywhere at least. Some of it isn't any steeper than a cow's face but it does tend to get brushy at times. Hell, we'll even let you commute two hours or more each way (for free), and get up early enough to be on the saw as soon as you can see the trees. As an extra added attraction we'll let you keep the same pace we do...start to finish...for that measly six hours. It's easy to stay ahead of the skidders if you just move at a good trot all day, don't get hung up, don't waste a lot of time falling down too much, eat your lunch while you're changing chains, and get your resting done while you're on your own time someplace else. All you have to worry about is keeping everything in lead and bucking stuff that wants to roll down the hill.
Look at the pictures TarzanTree posted where he's stretched out over a log bucking the far side. You'll get to do some of that. And you'll get really good at catty escape moves when everything breaks loose and gravity takes over. And after you're done...haul yourself on to the next one. And the next and the next and the next. Don't dawdle...if you're busheling you need to go hard to make any money. If you're day-waging you still have to go hard...the side rod wants wood on the ground...and lots of it. Oh, and there's springboards too. Yup we still use them. How's your knees? But hey, it's only for six hours, right?
So...come on out. Six hours a day? How hard can that be?
