First deer I killed was back in 1962 .... on an acorn flat in the midst of a several hu ndred acre cypress swamp in SE Louisiana. White tails definitely will cruise swamp land .... as long as there is decent browse year round, and it helps to have an acorn crop come fall/winter. They prefer to bed in dry area, so look for what I refer to as "flats" .... areas up out of the water ... for bedding areas. If you can find a nice trail to-from these bedding areas usually it works to set up where you can watch that trail.
