there is an awful lot to consider. what is the bulk of the mast? is there any? where is the thick bedding cover? where do they normally eat greens? wind direction for approach? I think i'd contact the qdma and or the county farm bureau for help/info. because in addition to food plots there are other things you can do/plant, fruit trees, mast trees, etc. you can also do things like green brier. you need a good balance for year round food to keep and hold deer. the county or qdma can help you with the big picture and with the fine tuning. like where the sanctuary should be. the shape of the plot is also important. figure 8's or L's. if you're going to do it i would get their opinions with boots on the ground plus there may be $$ available from either to help you make the improvements.
