During noon time hours I start scouting: Looking for tracks/ scat: If I find that classic 1' wide super recently used trail that almost looks like cattle have been in the area, then I follow it and set up and call if I feel I'm close, if I smell elk I will definitely set up and call according to how far in the season I am (call tactics wise).
I have a lot of areas I like to check on due to hunting the same few units for a while which I recommend: The more you get to know your area, the more you'll find bedding, wallows, rub nations and just places where elk like to be, so I check on these historic spots.
On top of this I e-scout my areas a lot so I have markers I've set up throughout the offseason on places I plan on checking out and dead noon times are great for this.
I rarely sit water but if I find a wallow that looks and smells active then I'll sit it, but the longer I hang out, the more worried I get that my scent is broadcasting so that's really wind/ thermal dependent for me.
