I lived in Western NE for 11 years, and spent a lot of time devoted to hunting and scouting goats there. during the archery season, especially early, rain will be the biggest issue if you're sitting water holes. that time of year it can be really dry, so a late July/Early Aug rain can really screw up your hunt as the goats can get water out of any little puddle and won't be condensed around cattle water tanks or ponds(if you find the rare one there). if you wait till end of Aug-1st Sept they start to Rut and you can have some opportunity to decoy them but this is a numbers game and you need to cover a lot of different herds and find the right one. If you go up to the NW corner of the state in the Ogallala grass lands, its easily the most concentrated area of antelope in the state. there is a lot of federal ground, and no need to knock on doors. it also gets a lot of pressure, so be prepped for other hunters.
