Load up on ammo and go varmit hunting. Equipment expense for our crops are outrageous (250k minimum for just a tractor or combine). When my mom was little we had about 20 hired hands, now we have one. The changes in technology and equipment have made it much more efficient.
Our little farm is bordered on three sides by a farm/ranch that is several thousand acres which is about 20 miles long and several miles wide. They grow a variety of crops, cattle, horses and elk. Everything is relative with the theory of diminishing returns or whatever it is that drives us.
