I guess I would have to communicate with himto find out for sure, but since I do not figure you have spoken to him, you will have to take my word.

Nah, I'll go with my theory. A wind shift got ya. You may not have noticed the wind change, but if the rain was coming and came that quickly from behind you, there were swirls or shifts. It dosn't do a complete turn around with the first rain drops. Sure they can hear, but something that far removed they'll usually hold tigher than a button until they figure it out.

I guess we will agree to disagreeDaniel Boone.

This may seem like a minor nit-picking point but he couldn't possibly have been 4y.o. in Nov. There's always going to be a 1/2 in the age in the fall .Oh yeah he winded you!

I stand strong on my original assumption. Cheese in the breeze.

That we will Grasshopper.

It sounds like there was a bigger buck in the area. Our he smelled you our somthing.

The way you stated he acted, he took a submissive posture.....my guess is a dominant buck that you never saw ..

i think there was a bigger buck in the area.

I am going to have to agree wtih DavidMil here, and since he is one of the more experienced members on this forum, you might want to listen to what he has to say or else you may have this happen to you again[8D]
Remember those summers when you were a kid? Hot summer day, then all of a sudden a cool breeze, then you can smell rain in the air. Happens often, since wind likes to blow out of a rainstorm, and into an area where there isnt rain (Isnt the saying wind blows from high to low pressure?). Hence, the reason you can smell the rain. That same wind carried your stench towards the buck, he smelled you, and bolted.
Also, quite possible he smelled a dominant buck in the area, and bolted.
Either way, the wind was the culprit!
