Don’t make this any harder than it needs to be.
Or make it as complicated as you want, with Mojo’s and decoys and blinds etc.
I’m in the middle I own a dove mojo, and 4 decoys but that’s just to increase my odds. As far as where to hunt them, Harvested Wheat fields are the best (IMO), but that is not the only place to find them, as mentioned above gravel pits, quarry’s, silage chopped corn fields etc. All you have to do is go find them. If your into goose hunting, they will share those same fields, and so starting with asking for dove hunting permission may build a relationship to work up to waterfowl.
I love dove hunting, and have done it since I was young, and when they are bacon wrapped on the grill it makes it all worth it.
