Milk jug cubby with suspended mouse in the cap ---but only after the coons are napping in January. Coons/opossums will find about any weasel set and render it non functional when they are out (they do for me anyway). Overly optomistic if you think you are going to catch many-if any, in Nebr. I spent 4 years in MN trapping and caught 20-30/year (short tails),,, most in dryland mink sets, all of which I brought back to Nebr. over Christmas Vac. and sold to taxidermist. Grew up in S.E. Nebr. in the 60's and 70's and only caught 1 long tail in all that time (Missouri River marsh). Handled 30,000 acres of CRP in the 80's - 90"s for USDA and saw only 2-3 tracks/yr. in the winter here. But--- if you have any in the Rainwater Basin there, it will be the cattail/frozen wetland edge that might harbour a few. Check for tracks after the snow-then set the trap. The advice from the Northern tier States Trappers is "good" but until they see the the conditions, topography, land use (with vegetation types) etc. etc., you have, it may not help you. When was the last time you saw a rock wall, tag alter swamp or overgrown forest edge in a field by Exeter? You do have the isolated wetland edge in the Basin which may be the the spot to start looking.
