does
 

Tonight I was out in my stand and saw a buck and a fawn walk out of the corn and then all of a sudden i heard a doe blowing and the buck ran off about 50 yds and looked back very nervously. I was about 75 yds down wind of these deer? I did walk through the area the doe was on the way to my stand. Could she have smelled where i came in and done this or is there other reasons they blow?

she could've gotten your scent.. If not there could have been a predator or something else that she never liked.

maybe another deer snuck up on you and was already nervous/had tail up. this has happened to me, basically they just signal the other deer and off they go. They could have caught your scent from you walking in earlier, thats some pretty nervous deer. like wisbowhutner said it also could have been a predator.

Could be just an old doe. Some just get a little nervous and go ballistic

Thursday night I had a huge buck walking towards my stand. There were about 10 does close by and one other younger buck. All of a sudden they all turned and bolted like it was scripted. No blowing, no stomping, just out of the blue. I think something else spooked them and they were gone. I wished I knew what it was.
