Mark, Do you find that your pans get exposed more in general covered in grass vs dirt? During the course of a year I think we all get some traps uncovered by animals (not necessarily coyotes) covered in dirt. Just curios as to how you think the grass compares in number of exposed traps. I guess my line of thinking is why not cover like that on every set and not just on pipes? An obvious exception being if you are setting in a solid dirt or sandy spot where the grass would really look out of place.
The steel screen, due to its "roughness" has a texture, and tends to grab the grass covering. While I like the way a set looks after I make it, I gotta admit, I like it even BETTER after some moisture gets in the grass covering, flattening it out, and making it look like a spot in the field that left a small pile of grass from the last cutting or whatever. Since the trap bed is so small, that flat area with the grass covering is small and acts as its own foot guide.....meaning, its just screams "Step Here!"
IF I made a dirt hole in a hay field, then I'd consider making it the same way............but a dirt hole in a dirt field might not look as good with a grass covering.....still, try it and see? You could fill hole with grass and make it look like a nest or something that was dug out.....
In a hay field, if I'm gonna make the set knowing bad weather is coming, I'd just as soon pound in a pipe vs. digging a hole knowing it will fill with water or snow or both!
