Just to answer a few comments made about waxed dirt, I have tried( for many years ) with some sucess dry dirt and salt, only problem is after a catch or any moisture the trap rust really bad and I always dealt with refusels, sometimes more than others, but had plenty.
I tried hulls, the were ok if you top dressed and got him to step in the right place on the first step, if not I had plenty of dug up traps, worked better in a step down type set where heavy guiding could be used.
Peat moss still got wet with our rains and than froze, plus I had plenty of refusels with it also, it also seemed to work better on a step down type set.
Dry dirt works fine for me and I have used it in the early season with good results.
I've got it from barns, under bridges, under root wads and out of corn fields in the middle of the summer and stored it, all worked fine.
Also tried variuos types of liquid antifreeze with similar results, wet pattern, refusels, etc.
My experiance with waxed dirt is as follows, it can rain and than freeze and at the worst I have a very thin crust on top.
It doesn't blow away anymore than any other dry dirt.
It doesn't seem to make the K9's shy away( I have quite a few 1st night catches using it.
As far as cost goes, I use a pound to the gallon of dirt, I get about 2-3 sets out of a gallon depending on how liberal I am with the dirt.
Its cheap compared to checking frozen out of commision or rusted traps.
If I ever find something better I'll go with it.
As far as the salt goes, 3 years ago in southwest Kansas we got some pretty good moisture and freezing and salted everthing pretty good to keep the freeze away.
This was sand country, once it started to thaw again the tracks told the story, lots of pattern refusals, really cut are catch fast.
I had been using waxed dirt here for several years and just didn't think that anything was needed out there.
When we saw the forcast we bought some salt and worked all the sets over(around 130 of them) it was a real eye opener.....B.....
