Need ideas for finding feedlots

Try talking to truckers hauling grain, sileage, and hay. They know where these feed lots are.

Call your local sales barn. They know all the feedlots and the ranchers in the area.

Marksman, for the past month I've been on Google maps searching (within a 50mile radius) around my home for feed mills, ranches, stables, Ag farms, golf courses, open lots/field. Must have called over 20-30+ places. Finally got a possible permission at a feed mill 20min from my house, also connected with an old coworker who has some property that would allow me to hunt on. If non of those places worked out, I was about to go door knocking (which I still might do).
Keep searching you'll only need to find one or two, then build your network of permissions from there. Someone also told me to ask the farmer or property owner if they have pest/rat problems that'll get your foot in the door (those folks love free work) from there you can gradually move on to pigeon, rabbits, doves.
Hope this helps. Good luck!

Farmers love when you get rid of pest gophers, ground hogs,wood chucks ext... There a real problem when a cow steps in to a hole and breaks its leg..

Check Google Maps, satellite view for feedlots.

Marksman, where are these feedlots "West of Dallas"? I live north of Dallas in Allen, might have to check these places out since they're relatively close to me. Thanks in advance!

Living in a smaller urban area (Roswell, NM) has it advantages, as we have a lot of exurban farming. I just ask my veterinarian about it, and he invited me to his place. That lead to yet another location or two, and just recently, to a 500 acre ranch less than 10 miles from my home. The latter is covered with just about every non-game animal you can think of. I'm dreading the cold weather coming, but I'll still be out there in my heated blind.
