It depends, I try and learn elk behavior for the season I’m hunting and apply that knowledge to the unit. For example, some areas are migration corridors and can be incredibly difficult to hunt if you are there in the early season. You basically have to move around till you locate a resident herd. Some areas can be heavily influenced by private/public boundaries and pressure. If it’s high desert, you may be sitting water or spot and stock hunting. I think it can be easier to master one season in one unit but if you’re hunting different times in the same unit it can be a totally different strategy depending on the time of year.
Lots of factors, just don’t hunt them like they’re a whitetail deer. I did that the first couple years out west and I didn’t punch many tags.
