Make a trip before the season and spend half your two weeks scouting. Roads, camp sites, access, what the timber is like, etc. E-scouting is kind of a joke for the most part. Sure it gets you at least something to go off of but it's nothing like being there. Everything you pin drop of areas that you think may be good, could be not accessible or take you 4x as long to get there. No way I would show up to a new state, new unit, and just hope for the best. Get all that figured out before the season. You will have plan A through E lined out and have a plan to get to those spots. Lots of roads or trails may not be what you think too. Get it all figured out before the hunt. Make sure you are always in hunting mode the second you leave camp. Don't just hoof it to your "spot" and forget about hunting til your there. I've passed way to many elk and busted them out because of trying to quickly get into an area we thought was good.
If you don't see elk, or elk sign when hunting, move on. Over the years I've spent way too much time in "awesome elk areas" with no elk. Saying, oh they should be here... water, bedding areas, cover, vegetation, etc. If they aren't there, move on. If elk are around, you will know it. 2 days of nothing, get out of there. I've killed elk early season from 6,400 ft to 11,800 ft. So don't limit your search to just one elevation.
For sure two tags. So many times the caller ends up with just as good of an opportunity as the shooter. Setup is everything but in a split second with no notice, the shooter may need to become the caller and now you're the shooter. Especially when other bulls slip in.
Number one thing is just to have fun. Don't get discouraged. Elk hunting comes with the highest highs and the lowest lows. You can have 6-10 days of total suck, and then all of a sudden get it done. Just always be ready for an opportunity. They don't come often and take advantage of the ones you get.
