I thought you'd be taller. Kidding. Looks like you're aging just like me...like milk.
But yeah, mule deer, especially rutting bucks, are about as easy and forgiving as it gets. I've got a whole pile of them with a bow and understand them fluently, been photographing them since I was about 12 and understand them intimately. You act like you belong and don't care and you can dang near walk right into the herd, hard to explain but anyway. Whitetails don't walk away. Haven't noticed elk walk away much either. As soon as whitetails they pin you down the clock is ticking very fast, and I mean fast, usually you must spot them before you and just you getting over the pack or settled into sticks is all time you'll get, if they spot you first it's flags and goodbye immediately. They don't walk, you get a few seconds of them processing at best, think coyote, and you get the idea. A lot of whitetails are shot non-stationary, as often the only way to fill a tag.
Helluva deer, strong backs! 190? He'd fit right in with a bunch of mine.
You coulda walked him down another fifty and spudded him with an iron sighted 30-30. Joking, but I might be right lol.
