Find the mast and you will find the deer when season rolls around. From what you say you know where they bed, so now it is a matter of setting up between the mast trees and the bedding area. Not knowing the lay of the land and if there are crops in the area makes it a bit difficult to help. If the concentration of mast is in an area away from their summer forage then the trails they use will probably not be well defined right now, but if you know where the trails were last fall between thier bedding areas and the mast crop then you should be setting up in that area, make sure you keep in mind that the prevailing wind sometime changes so you will need to set at least 2 stands to start with and be willing to fine tune the locations due to minor changes in their travels and wind. Oh yea and once the rut is in as others have said find the does and the bucks will come.
