I'm a big fan of not telling the world. I've lost hunting spots because others knew that I hunted in that spot and did well. I'm not sure about everyone else but I've got a huge time investment. Don't really want to say how I've spent my time but it is way more elaborate than google earth and I know most guys that are pretty serious have done the same. The money part is pretty simple. I hunt a ton in AZ out of a camper. Finding back country hunts in this state is a bit tougher to do than in other western states. Most units I hunt you struggle to get 2 miles from a road. Since I hunt out of a camper the gear that I typically use is very different than the gear I will need in the unlimited's. Pack, clothes, boots, stove, tent, sleeping bag, water filter, battery pack, in reach, ect.........the list goes on. It can be a fairly large financial investment. Not even going to count buying a lighter rifle w/ scope and money I spent on optics.......please don't tell the wife.......Cool part is this gear can go on a ton of different types of hunts in the west.
As far as a unit. I've looked into two different units. I literally had my heart set on a unit and then after a conversation I looked into a different unit that is probably a better fit for me. It can be different for everyone. I'm not married to the unit but I do have more than a little time invested in to researching both units. Another bigger time investment is learning about sheep. Better know where they typically eat and live in mid September. It changes by season and is very important to know. It's big country and if you can spend more time looking in the right spots that might help your chances.
OR......I could look at the mountains. Pack my crap up and head home because I'm a complete sissy. The possibility exists.
