We have been very dry this summer as well but at our hunting ground we have a river that runs through it. In past summers, the river hasn't played much of a factor in deer movement, but after some scouting last weeked, it is evident that due to the dry conditions, the deer are really using the river as a travel corridor and obviously for much needed water. I hung a stand off a trail that parallels the river in hopes of a brute passing by on it. The river noise is also a great cover. The water holes though are truly spots that can be productive all day, especially in the warmer days of early season.
