well i was in my stand (my stand is located on a field edge which overlooks two small fields) this afternoon and at around 5:15 a big buck comes from out of nowhere at like 15+ yards. im looking the other way and when i see something i moved my head over to it real quick. when i moved my head the buck stopped in its tracks and stared at me. we were staring at each otherfor probably 10 minutes and then he started sniffing and it stomped its foot a couple times. it then kept walking like normal, and i moved to try to turn and shoot it but he bolted i never got a shot off. i dont think he smelled me i think he saw me. im really frustrated about it. this deer is probably old by the huge body on him and by the size of his rack. what did i do wrong? and if i hunt there tomorrow afternoon as well will i have a good chance of seeing a deer? give me some advice
thanks
