Some folks have kind of dabbled at it, but I love glassing hard middle of the day. like 12-2 pm. I started doing it because deer re-bed around then and kept picking up elk. So now I do it for elk, too. They often get up and stretch their legs, grab a bite to eat, and sit back down, too.
It's also just a fun game to play of "can I find a tine in the shadows" and that keeps my brain occupied. It's not the most effective, but I'd rather not get my stink everywhere if there's not good tracking conditions.
Granted - this is if you're looking into burns, broken terrain, sparse like blowdown timber, or aspen country. Hard to do with a thick wall of timber. And I build my hunting plan around being able to do that.
