If you didn't feel like the hunt was a challenge, then it probably wasn't fair chase. Some of these high $ outfits in S. TX have lost that quality in the name of big antlers and big dollars. I personally wouldn't hunt if I had to have a guide to tell me whether to shoot or not, or if I had to pay based on antler size, and don't think I would feel like I was hunting if most or all the deer came in to a feeder on que.
Don't get me wrong, I use feeding, but where I hunt it is a far cry from deer showing up on que. Days may go by before you see any deer at all, and many times they aren't interested in the feed when they do come through. The feed does two things that I consider fair chase: 1) causes deer to pause in shooting lanes or in shooting range so that I can evaluate age and antler quality before shooting, and 2) encourages more frequent (not constant or automatic) use by deer of the general acreage I am hunting. It is certainly not a "sure thing" to kill a deer, let alone a trophy buck, because I feed wildlife. Coincidentally, deer probably eat only 10% or less of the corn I feed. The rest goes to hogs, varmints, and birds.
