I was lucky enough to pick up some land this last summer at a real estate auction in Northern NY. Bought a house and 5 acres for under $5000.00 (my severence pay for when my job went to China). It's in a small town and don't know if it's useful or not but would be more than willing to let a unit do some training there.
I guess more importantly is the price I paid. Anyone up this way should check the auctions out this year. Might be able to pool some money and buy substantial acres. A lot of the cheaper properties sold were "land locked" and you have to hike in to get to them.
