If you have the fence for them, I hear goats work real well. They supposedly love the stuff. Then you can get a return on your investment with a bbq in the fall.
I agree with BTDT on the goats. Two TN fainting goats, some temporary electric fencing & you won't be worrying about the ivy.
Our first place was a 4 acre poison ivy farm in NW PA. I cut vines 4-6" thick & carted them off by hand. I also got the itches real bad (Dr visit, steroids, etc). Use Tecnu for any contact with posion ivy (tools, clothes, skin, etc.). A bush hog might be a little big to wash down, especially underneath. But it works well for axes and the like.
Ben Meadows sells the stuff (get a few friends together for an order and reduce the cost)

I used Round Up, Super Concentrate and mixed the stuff to brush strength. That worked well for me. You just have to be persistent (more so than the plant) as continual maintenance is required & the stuff spreads by vines/roots/seeds. Once past the first year of mega-spraying, the maintenance spraying is much easier. (Our company arborists recommend Brush-B-gone as well.)
As has been told, burning releases the oils into the air. Breathing the oil coats the inside of the lungs and can be deadly to some people.
Soon, I'll have to clear a trail (with poison ivy) between our house & the farm. I'll probably clear it using the brush hog & then just avoid getting my bare hands underneath it from now on.
Your area of the country is quite beautiful. My better half & I visited there on our first vacation. Has the lake monster been spotted recently?
Good luck, be safe, & let us know how it goes.
