The 1st question would be does the OP intend to make this a money maker. Or is it just personal ambition.
he's smart to do the homework & post in the forum beforehand. My mt neighbors sometimes shake their heads when they see how much i put into my place w/o financial return.
But i won't attempt to try to exterminate, poison, or shoot feral hogs (1st & 4th pic) cause i know they'll be back. much prefer to enjoy the north pond (2nd pic) on the way back home today. the 3rd taken yr ago. i'd love to see the marauders gone as the OP intends to gophers, but have learned to accept & back drag as needed.
best regards to OP re: hay ambitions, document your progress & post, cheers
