JMO, and should be valued as such!
If your hunt state is Wyoming.....the G&F site gives information about the percentage of government ground and ease of access. The more
Extended hiking is generally "not" required......having an area with lots of road or two-track access is a plus. You are much better served driving and glassing......save the walking for the actual stalk, if needed!
Bring camping gear, an rv is great! Rather than spend money on motels and restaurant food.....live near or in your hunt area. This also provides you with much more "rest time". 3 or 4 days of hunting all day, coupled with the travel time to/from your home base (motel) will quickly take it's toll on your energy reserves. Add to this the elevations you may be dealing with, will also add to your fatigue factor.....a good, long nights sleep will quickly become a priority!
Good glass, it doesn't have to be the best European, can help you find and determine the game quality.
Clothing: Again, I'm referring to Wyoming.....expect any weather condition you can imagine. Temperatures can run from single digits to 80's/'90's, from dust to mud, snow, rain! While walking is not generally mandatory, two pair of well broken-in boots would be great. If things get wet, one pair drying while you wear the other. Also, if you tent camp.....bring the best, sleeping bag you can warrant. Quality boots (no sore feet) and a good bag (good rest) can make your hunt much more pleasant!
Firearms: nothing special needed. Use whatever you feel very comfortable with. Anything from the .24's ( some states allow .224's) to big magnums work nicely. Just be prepared and comfortable out to 400 yards or a bit beyond.....and you should be fine!
A GPS with the program showing hunt areas and property boundaries can also be of some help!
Well, that's a few of my suggestions! memtb
