Similar thing happened to me on Sat morning, he didn't blow as long. Check the cameras on Sunday and the mature 8 that was showing up to where I was hunting ended bypassing and going to another feeder. I was so disappointed. Yet another reminder to check the wind! After 20+ years i need these reminders.
Forget about the blind... if you really want him hunt on the ground. I Hunt on the ground 90% of the time without a blind just up under a tree with some brush or cedar limbs in front of me. Get good camo and face cover, buy a good swivel seat that is silent and comfortable. Think about when and where you can draw without him seeing you. Throw some corn out where you want him... let em fly.
Making your draw is really the only point being up in the air is super beneficial unless you don't know where deer are coming from... You know his route. Keep playing the wind. Even up in a tree they can see motion fairly easily so just have to perfect the skill. Learn not to look at every twig snap or acorn drop. Time your draw and be able to hold it if you have to. Practice in your head how it will happen in a few different scenarios. Is he coming in and not stopping ? Does he come across at a different angle? On the other side of this bush or that one? Then think about when and how you will draw in each scenario. Sometime jus the corn is enough with their head down for a second. The same stuff you think about from up in a tree your just closer and easier to see but it also makes your shot closer no angles. No cell phone games or other bs. Plus mature bucks are weary at feeders he will be more unsuspecting walking down the trail you just better be ready or miss your chance.
