You might want to list where you drew the tags in since antelope are present in quite a few states, so state and unit number and hunt, archery, muzzleloader, or rifle. Then we might be able to get you going somewhere.
If after scouting for 3 days you locate a very nice buck try to nail him asap as they will get moved around fast the first days. But if they are all pretty much the same size then take your time and enjoy the hunt. Getting a buck in unit 3 is not a problem ,its not if but when so take your time. speed goats are more fun to watch then shoot.But have a cooler ready with some frozen milk jugs and get that antelope skined and in it fast, warm temps and no shade they don't last long.Don't forget tire chains maybe for all 4 ,if it rains the roads up there get slick beyond belief. Have fun and be safe !!
www.huntdata.com and the NDIS Map it! link on the CDOW website are the most useful things I have found. I drew a CO muzzleloader tag that includes unit 3. That is where we will be hunting because their is more public land than the other areas included in my tag. From what I understand the Northern border of unit 3 (stateline) borders the best units in WY. You may want to consider heading farther North and the major water source is the little snake river.
Out here in Colorado, and in the units that I haunt, it is a tricky game to figure out how far to pack in on a rifle hunt. You want to get away from the masses that have moved game away from the roads but might want to stay close enough that you are taking advantage of the animals forced movements. There is no universal distance but I like the 1.5 to 4 mile range for day hunts where I am not planning on bivying out. This keeps you in that productive buffer zone where the animals are really...
