How much timber do you have on your property? You said that there is limited amout of timber nearby, but did not say how much you have. I don't know if you have any creek beds or fence rows, but that would be a good starting point. Watch the fields in the evenings this off season and that should give a good idea at what kind of herd you are working with. Hunting small timber is no different that hunting big timber, find their bedding area, preferred feeds areas and find a good ambuse spot in between.
