I've got a lot of spots i test lures in (mostly right on the edge of low maintenance roads) but these sets are all within a half mile of my best test spot. I got proven formulations that I haven't tested for years so they are mostly new to the majority of the coyotes here. But I do have coyotes here that are pretty smart to a set with a trap in it. I don't catch them all and that's alright because I need some to develop lures on.

The less cautious one i bet I could put out a lure or bait in a test set and come back in a month and catch them on they same stuff though.

I got some that will work a test set hard but won't work a real set, which I found darn intresting and some that won't come within 10 foot of any kind of lured or baited set.
