Unit 2 has lots of BLM land, so we just camped up there - get a few BLM maps and you'll be set. We were close to the Wyoming border, in the more north west corner of the unit. The little snake river area was much farther to the east, but that also looks like a good place to hunt, with more possibilities. I think the more southern migration route is probably more productive. Due to the warm weather this year, there just weren't many animals that had moved west. We hunted the draws and looked for animals that were moving between their bedding areas and where they were feeding, mostly in areas with lots of pinion pines. In these areas, they seem to like hanging around the draws and feeding on top of the mesas. There weren't too many high locations to glass from.
The shot I made this year was 475 yards. We had spooked a small herd off the side of a draw, and then pushed them into a feeding area on top of a mesa. I wanted to get closer, but there was litterally no cover. I crawled along until I could find a nice location to shoot from, lased them and then dropped a nice cow. The lack of cover in these areas makes it hard for any shots under 200 yards. I would get some shooting sticks, and practice with those also.
Funny story: We didn't see any additional animals for 4 days. We were all over trying to spot another herd. On the last day, we were heading back to camp, and just as I turned to where our camp was, we spotted a nice herd. I actually just drove my truck into our camp site. My friend had a nice 340 yard shot, but jerked the trigger and wound up missing. It turned out that the herd had actually walked through our camp site.
