It depends on where I am. If I'm in the riverbottom, I get down and go home. No reason to stay, they can only come from 2 directions anyway, and 1 is MUCH more prevalant than the other. If it switches to the east while I'm there, I get down.

Some of my other spots though, they come from any and all directions, and from what I've been able to conclude there is no perfect wind direction. So I stay put.
