Sorry, should have elaborated, just busy.
Cliff said that you basically shouldn't have any expectations other than you could possibly get lucky and/or a bull might make a mistake.
I think a "majority" of luck is made, not all, but a lot anyways. Yes on occasion people get lucky here and there without doing anything right.
IMO if you put forth the time scouting, do the right things (basic hunting skills), and work hard you should EXPECT more than just a camping trip. Speaking for myself, I've hunted CO, WY, ID, NM, and MT for elk. I've killed bulls in all of those states on my first trip to the unit except MT. The weather beat me in MT in 2015, so I pulled out early and went to CO for an OTC unit and had a great hunt. In WY and CO I've hunted multiple units, again killing elk on my first trip to the unit. On two of those trips I killed bulls the first day, on two other trips I've killed the second day. All of my trips are DIY, public land.
I'm not saying it's easy, not at all. Just saying if you plan to go into a hunt with no expectations, and that if you do connect it will be just blind luck that a bull made a mistake, you are setting yourself up for failure. It's easy to have excuses ready before arriving, and that just makes it easy to work half assed, throw in the towel early, etc.
Have multiple plans ready, be prepared to work, and expect to kill one.
Good luck.
