You know that corn is worth a lot when farmers are converting huge chunks of overgrown (bush) lots back in growing corn.
My neighbour paid $1,200 an acre to clear 40 acres. With crop yields of about 175 bushels per acre and sale at $5.50 a bushel, farmers can pull in $1000 acre. So it will take a couple of yrs to pay that off.
In the mean time he's cleared 40 acres and will make a huge food plot for me to hunt on. :)
